Default Be a hero, Help a disgruntled man :P (ignition probs)

Well I finally made it hope a trip which should have taken 5 mins took 5 hrs...

The Problem...

I have a 95 Camaro LT1 It is modified pretty well..

Cold start Runs amazing and for 5 miles it will continue... after that time... The car will Die.... tac will sometimes jump crazily right after car has died...

When i try to start the car.. It won't..... If i let it set for 5 mins... it will run for another few minutes.... Repeat this cycle till you get home

I replaced the msd blaster coil... problem remains
Replaced the ICM ..... Problem remains


Usually i don't come begging for help but now i am... I need some other troubleshooting ideas... I don't feel like getting stranded 10 more times...

I do have a 6al box... Thanks for your help guys...

is it throwing any codes? It sounds like whatever your problem is it is happening in closed loop but without reading codes we are kind of shooting in the dark unless you want to start throwing parts at it

Check your fuel pressure. By that I mean get a fuel pressure gauge and put it on the engine to see what kind of pressure you are generating. It reads like your fuel pump may be overheating. Keep the guage on the car when it acts up and check pressure. Try to do it with the vacuum line off. Pressure should be in the 43 to 45psi range w/out vacuum.
