My Dodge Van has an intermittent problem. I start the engine and then try to move and the engine does not respond to the accelerator. It is a dodge 3500 with a V8 2001 model. When I restart the engine it will perform in a normal manner. Any ideas?

That may be a "fly by wire" throttle. Your pedal "talks" to the PCM, which in turn opens the throttle. The two may not be communicating consistantly. If you have traction control, that may be part of the problem.
Did Dodge have that in 2001? I don't think my 2001 Ram is fly by wire. My 2004 Durango is.
My 2000 Ram is.
Of course, the TPS would be another place to start, and really, getting the codes via the KO/KO 3x method would be the best place to start.
Must be the Eggnog.....
That's because your truck is, well... different :) And even so, you still have a cable going from your pedal to your APPS - just as I do. Cummins-powered trucks didn't go true "DBW" until '05 (hence the funky little TV motor on the tranny, instead of the cable-actuated valve)
The 318/360 are always mechanically-controlled throttles, as they have an actual throttle on them.
True - any stored codes might be helpful. I would think something other than a TPS, though - even if the TPS was bad, within a short period of time (sub-second), the MAP sensor should detect the higher pressure caused by opening up the throttle plates, and cause the PCM to adjust the fuel accordingly.
