When driving the vehicle on the highway the truck starts slowing after several miles of driving. The speedometer is decreasing and when pedaling on the gas to speed up with traffic it doesn't, just the RPM's starts to go high and low. We've asked shops and they start guessing at the transmission or the fuel pump. Any clues on what it could be?
