I will be driving and my truck will just lose power. I push on the gas pedal and it goes no where. I have to coast off the highway and then I can stop and turn it off for a few minutes then start it back up with the check engine light on. I have changed the tps 2 times, the entire throttle body, and the mass air flow sensor and it's still doing it.
