Engine Mechanical problem Automatic 63,300 miles
while driving after 20 minutes the check engine light will come on and it will read engine power reduced at which time you can't go over 40 miles an hour, so I pulled over and waited a minute and restarted it and it runs fine and happens again 10 or 15 min later. Today I tried to drive through it and it ran fine for about two minutes then said engine disabled, pulled over waited a few minutes and restarted, ran fine. Took it to napa auto parts so they could run the code and it was p0641. Let it idle for 20 min and it said engine disabled again so they unplugged the mass intake sensor and decided that it was working. The chevy house said they couldn't get it to do the engine reduced power. Any suggestions
have the same problem?
