If this is vapor lock, typically the stall would be proceeded by a stop 
(like running in to a convienience store) of 10 to 15 minutes, with very 
little run time after you got back in the truck. Typically just down the 
block. If the stall is on the highway after driving for a while, suspect 
debris cloging the sock in the tank. Once the vacuum holding the debris 
to the sock dissapates, the debris falls off and the truck restarts 
fine. This condition is exaggerated by concrete roads and other slightly 
rough surfaces.
