from what i see in the video check inside the steering column for any loose wires or anything loose in the engine bay, on some of the videos the whole dash cuts out and then starts back up just like when you start a car up the first time, notice the air bag light and other various lights that occur on start up, it happens here too.

look on the last video when the engine dies so does the speedometer, if the engine dies in a car the speedometer and everything else should keep working unless you have something not keeping the dash and everything, its probably a loose or melted harness and the only way to figure that out is to comb through the engine bay, steering column etc...have you checked inside of the steering column, might be something wrong with a wire in there telling the engine to shut down or something, it almost looks like more than one problem.

then not that im making this long enough but to check the fuel pressure would be a very good move, my mom had a bonneville that when idleing it would jump from like 1K then to 2K and then almost die then back up to 2K then level out, run right for a lil bit and then do it all over again, my dad took it to the dealership and they found out that it was the fuel pressure regulator, letting too much fuel in, then not enough, kinda looks like the same instance.

Somethings loose, your alternator, or a sensor is bad.

Those are my three guesses.

On the way to carlisle, my car would run fine for a few miles, then begin to sputter. Slow down on the highway for traffic, it would die. You could feel a misfire, but I had just replaced a coil pack and the IAB. I was getting codes for the MAF and TPS. Replaced the TPS, still a problem. I could feel it start to go bad, throw the car in neutral, turn the key off, coast for a few seconds, turn the key on and put it in drive, would be ok for a few more miles. While in Carlisle, replaced another coil pack on a guess (8) and reset the computer, was fine after that. Developed another miss on cylinder 2, few weeks ago, went to put the brand new coil on cylinder 2 as it was the one always giving a problem, checked the sires and they had melted a bit. Insulated them. I have no miss and the car runs perfectly smooth now.

ok well mine is doing just about the same thing just replaced a few coils but nothing is melted i got the intake off right now making sure that no wires are melted.. none were....

but now there is no ses light on o nothing and its still stalling out.. just about the same as yours

so the only thing that you can say that could have fixed it was that ther was bad coils... mine are all good just replaced 2 of them and the others tested good

well 4 of the rubber cuplures were all broken replace them.. and it didnt fix anything not that i thought it would.... but thats all repaired.

here is another video of the car running like pooo
ONCE AGAIN THE KEY IS BEING TURNED ON AND OFF :)
http://youtube.com/watch?v=xTrem4Rt2lo
the more the car bogs the more gas pedal im giving it .. if i only push the gas pedal like 1-2mm down it will rev up higher..

i also noticed that it didnt really do it when i first started it up and the car was cold.. then once it was shut the car off and let it sit it started to act up...

When you turn the key off and on you are resetting the PCM. Then it will go to the hard coded cold start fuel tables. Once the PCM sees that the ECT is saying the engine is warm it will then go to the learned adaptive tables.

This is controlled by the O2s and the MAF.

If you don't have any codes that show up then it is a hardware fuel problem my best guess.

(ran fine till this last week or so) the pcm says reman on it (and i didnt replace it). the people b4 me owned this car for less time then me.. and i have only put like 10,000miles on it.

Well if there are any codes let us know otherwise I would be looking at fuel pressure.

DH15 CONTINUOUS MEMORY DTC P1121: TP SENSOR AND MAF SENSOR RATIONALITY CHECK
Continuous Memory DTC P1121 indicates the TP sensor is inconsistent with the MAF sensor.

Note: Throttle Position Sensor A (TP-A) is the same as Throttle Position (TP) Sensor.

Possible causes:

Damaged TP sensor.
TP sensor not seated properly (almost completely detached from throttle body).
Air leak between MAF sensor and throttle body.
Attempt to start engine.

You can guess all you want but if there are codes still present then that is the way to go.

The MAF is hard to test but the TPS is easy using a volt meter.

this is the only code there is

like i was saying the MAF is pretty new got it brand new from fords 3 years ago (even thos the car was broken for like 2 1/2 years)

and also like i just said i just bought the tps yesterday because it pulled a code on that..

and then today this code show'd up

what would you do or try

how do you test the maf i know how to test a tps but not a sho tps.. do you gotta have a flow bench to test maf's

Unplug the MAF. The car should run based on fixed tables in the PCM. If unplugging it shows no change then I would think it is good.
