My 1990 Olds Cutlass Ciera 3.3L V6 runs fine for about 10 minutes until the engine gets "warm", then it stalls out and will not restart unless I let it sit awhile. Then the same thing happens again. About a year ago, I had this same problem and in the process changed coolant temp. sensor,mass air flow sensor, fuel filter, fuel pump, fuel injectors, throttle position sensor and fuel pressure regulator before finding out that my code scanner was not picking up a code for the crankshaft position sensor. (for some reason the ECM was not storing this code?) CPS was replaced and the problem apparently fixed. However the problem has returned although not entirely with the exact same symptoms(close enough to make pretty sure). Anyone with any experience in this problem with related vehicle please let me know. I am going nuts trying to figure it out, and have a limited budget to repair this car. Thank you for your time.
