My truck runs but wen it gets hot it spudders but the car stays running but I have no throttle but it comes in an out meaning I push the gas but it won't accelerate an then I'll suddenly get power n lose it I have to shut the car down for at least 20 min or so just for it to be able to drive fine I've already replaced the batt like three time just changed the alternator n I still have the problem

All of the fuses at the glove box are good and there is no information about the relays and fuses behind the battery at the fire wall. Not sure which relay/fuse I should be looking for.

Need help asap

I recently had my air bag sensor replaced and since then my heater control valve has gone out. is it possible that the mechanic broke it during installition of the air bag sensor?
