You have 2 pairs of 3 twisted wires going from the pedal sensor to the ECM. You most likely have an intermittent open or short to ground in the wiring outside the cab and somewhere near the engine. Start with a thorough visual inspection of every inch of the harness at all contact points. Look for exposed copper even though it may be just barely thru.
