86 5000TQW - WARM START PROBLEM

["Remington, John" <John.Remington@pipe.nova.ca>]

I have an 86 5000tqw that struggles to start when warm.  

Some of the symptoms include:
  -when cold, It starts just fine
  -It runs just fine (warm or cold) 
  -while warm, if I shut it off and restart immediately, it will start
  -while warm, if I leave it for more than 15 minutes it will not
restart.
  -pumping and ramming the gas pedal through the floor does not change
the
outcome of the previous scenario. 
  -after applying some throttle or pumping the gas pedal, the spark
plugs
are still dry as a bone.

IDEAS?? Thanks,
