Turns on stays on for about 4 minutes, turn it back on turns off again. Once it stays on can drive a half a mile then loses power, quickly turns back on drive half mile turns off. Sometimes I can use it all day with no problem.

Things I’ve done, replaced high- and low-pressure gas pump, throttle body, air flow censor, cam and crankshaft sensors, new battery keep in mind no engine light never turned on.

Used it today no problem, yesterday couldn’t go a mile with power down, when on a good day car runs awesome.

This problem is the most difficult to find since there are so many things that can cause this. Even though there are not any warning lights on, I would still run the codes.
