Occasionally (1-2x/week) our truck's accelerator/engine doesn't recognize any movement in the gas peddle. Just sits and idles .... gears shift fine .... almost like the "sensor" associated with the gas peddle isn't recognizing any motion. Thoughts?

What is your question?

1-2x/Week ..... car will cut-out or not accelrate ... almost like a sensor isn't recognizing the foot peddle is moving/depressed. Car/engine just idles ... shifting is fine during the "idle" .... normally with a shut-off and restart of engine everything is fine .... if car is rolling when occurs then pumping the peddle rapidly for 5-10 seconds causes the accelerator to re-engage. Thoughts?
