96 sc300 will run just fine for about 20-30 mins and quit. Restarts right away and will go for a bit and quit again....replaced the relay-efi, fuel filter....any ideas are greatly appreciated here...what could be the issue?
Does the car die while driving or when its just parked? If its when you're driving it, it could be anything from fuel filter, air filter, and most likely the catalytic converter.
I agree on the fuel pump ECU being the culprit. Perhaps, there is a bad ground for the ECU or something similar. We had a similar problem with our generators out here; they would die after a half our and have dry fuel lines. The pumps would spaz out from bad grounds and eventually just die. My .02s
