Car trouble, need advice please

[whiteman_01]

I was leaving menards in the sho yesterday, and as i was accelerating my car skipped a few beats. It felt like the motor compleatley cut out for a split second then came back. It happend a few times pretty quickly then went away. Well i stopped at checker for somthing and when i left there it did it again. I then headed for home just easing it on to the highway and it didn't do it again all the way home.
Once i got home i ran the codes in my car and came up with this, 157, 172, 176, 177, 332, 543! so ok, i think the first few are because my maf sensor harness does not like to stay on, it works itself off because it doesn't clip tight. The egr code has always been there and i have done the valve and the sensor but its still there. So i guess my question is on the 543. "Fuel Pump (FP) circuit open connection - Electronic Control Assembly (ECA) to battery." This came from my code book. Any thoughts on what this could be??? I just did the fuel pump about 2 weeks ago. Any help would be great, thanks in advance.

when u are driving it does it feel like it stutters but very suttle? watch ur rpms when ever this happens does it drop? has ur cps been replaced? when my car was doing this the cps was going bad and over time itll get worse and worse to wear the rpms are dropping so much that the car bounces. changed out the cps and was back to normal, btw i was also getting the fuel pump code. i hope this helps im sure some more people will tune in and add there .02 cents.
