I own a 95 Caprice Classic 4.3L V8 Engine with 130,000 miles. The car start great, runs great when started, however, when the car reached the operating temperature, the engines will just dies with no symptoms at all.
When restarted, the engine will hesitate,jerk, buck,runs very rough and dies, its a stop and go and dies condition at this point.
I have to let it cool for at least 1/2 hour and it will run great and then the problem cycle again.
I replaced the ignition module and fuel filter but it did not help. The fuel pump was replaced 14 months ago.
I am going to replaced the Engine Coolant Temperature Sensor this week and hope this would sold the problem.
If anyone has similar problems in the past or knows what the caused is, please e-mail me.Thanks

Is the CEL lit up or are you hitting any codes? AutoZone will check for codes and give you a printout off what to check and how to troubleshoot it. I think if you disconnect your battery for a few minutes, that will clear the codes, so when you get your car checked after it acts up again, only those codes will show.

Check the connection to the maf, mine was loose and it would die after hitting a bump.

;) I replaced the engine temperature coolant and still doing the same thing. My next move is to test the MAF Sensor.
NOTE: How do you test if the PCM is faulty and if you replaced this with a remanufactured PCM, can you reprogrammed yourself? or if replaced the PCM from junkyard, do you need to reprogmmed it? Thanks for any advice.

Have you checked the thermostat? It might be that simple.

It might be cheaper to pay someone to tell you what's wrong with it, than to just keep replacing parts till it's fixed. I take my vehicle to a GM dealer and ask for a diagnosis only.
I have a Venture that used to sometimes stall off idle, and show a check engine light. A GM dealer after diagnosis told me that it was my camshaft position sensor, and then quoted over $700.00 to fix it. I said I can't afford that right now, and took it to another GM dealer that replaced it for $119.00. So, get a diagnosis only, and then shop around.
