Hi Scotty, my girl friend has a 1995 Chevy Lumina 3.1 with 90,000 miles when the car is driven 15-20 minutes it dies and it won't restart or if it does restart it does again until it cools down. The temp reads higher than normal and will show a low coolant light even thought it is full, the idle is high but sometimes it goes t normal then dies. I hooked up my scanner and noticed that is shows that the quad driver 4 shows that it's bad.

Yesterday I had a fuel pressure gauge connected and I started the car and let it idle for about 20 minutes then it died the fuel pressure stayed at 42 psi until it died. The fuel pressure went up when it died which I'm thinking that it went up because no fuel was being used, so the next thing would be to check for spark. Let me know your thoughts. Thank you

An icm is $100, thats a bit much to take a chance

I had thought about replacing alot of things including the icm but I don't want to just keep throwing money at it. this problem is only when it gets hot.

Could have an ECM issue, also look into the ICM as well. Those pre OBD2 GMs are a pain to diagnose...
