NEED HELP

[FEARNONE30]

I have a very strange problem. I just got done with my 60k top end including cam seals. The car fired right up and ran great for about 5 minutes and then shut off. Started right up and ran for about 1 minute and shut off and never started again. There was some bogging or slight popping sound in the air box right as it was stalling. I have done this to other SHO's and know what I'm doing. I put a fuel pressure gauge on it and it carried between 35-39 psi. Checked for codes and there are none. This car acts like it is running out of gas or losing spark. Has spark. New CID sensor also installed due to the oil soaked old one. Please give me some suggestions. I put new felpro valve cover gaskets, motorcraft wires, and plugs and all the valve shims are in spec. This is fuel or ignition related. Thanks.

Just thought I might throw this out there, but did you use the Chiltons for the Spark plug wiring? I did, but caught the mistake before I put the intake on, thank god.

I hate that freakin book.

Did you verify the integrity of all the grounds from the DIS to the firewall via the crossover tube and the grounding strap?

You need to physically check for spark. Pull a wire, stick a screw driver in it, and hold it against something metallic on the engine. Have a helper crank it. If it sparks, you got spark. Also, even though you have fuel pressure, that doesn't necessarily mean the injectors are firing.
