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?

Thanks in advance.

 

Moved to forum marked "engine".

 

need more details. does it sputter when it runs? how does it just die? is it an instant death lol? or its a gradual power loss and then shut down?

 

runs solid, doesn't sputter, gradual power loss and shut down within seconds....30 seconds later re-starts and runs for a bit...thanks!

 

well dont think its the battery or starter or alternator problem... sounds like fuel problem?

 

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.

its probobly a fuel pump ECu, very common........

 

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
