Car starts and runs. Once it's warmed up, the
Wouldn't think sensor or computer problem , more likely an ignition module . When it dies pull a plug wire an check for spark ,i think you will find no spark . Just from my 30 years of diagnosing GM vehicle's this has been the #1 cause of a start an run till warm an dies an wait 20 min . to an hour an it starts again problem. But without testing to know for sure that would be a guess . Having a qualified an certified repair technician diagnose the problem is always the best idea.

Saturn starting problems
u should check the specs on the coolant sensor & ck for vacuum leaks. When u step on the "gas" u are really controlling the air intake, the fuel injection is controlling the fuel. A bad coolant sensor or vac leak will give u these problems also. ck emissions when running. Good luck
I have a 2001 Saturn
Does the electric engine cooling fan come on when the temperature rises? If not, it could be a bad cooling fan. Check for power and ground at the cooling fan connector. It could also be a cooling fan relay.
Why can't I get rid of P0302
P0302- Fault Cylinder B-Misfire Detected (CYL2)Not sure what happened to my computer as I write this but it went crazy as well. Now back to the subject. Some of the new fuel injection is causing problems the way they put fuel in the cyl. by putting it in the cyl. over the valve instead of under the valve. This will leave a carbon deposit on the valve and not allow the valve to fully close and thus cause the misfire code to be set. I just went through this with a v/6 3800 cid I had. You will need to run a valve cleaner through it to remove the carbon and then reset the ecm and drive the car about 50 mile and cycle the ecm and then see if the fault comes back on. Hope this helps.
