2003 Chevrolet 2500 hd truck experienced an engine power reduction. The vehicle operated at a reduced speed. It goes at a crawl. This occurred at speeds of 40-50 mph in the middle of traffic. Has to coast over to the side of the road, on average about 10-15 seconds after cutting off then the engine restarted. This usually happened after vehicle has not run for an extended period of time such as being parked overnight. Took to a dealer, who replaced the accelerator pedal that ran by wire not cable. This was electric and computerized and some sort of signal went through the accelerator pedal and caused this failure. The vehicle will idle, but lost power. This has been a problem for the last 3 months. The problem recurred even after the replacement of 2 accelerator pedals.
