Yay! My thousandth post!
Sounds like possibly a vapor lock situation. Check the routing of the fuel lines to make sure they aren't resting on anything that gets hot enough to boil the fuel in them when you shut the truck off.

Welcome to FTE Steve. Please note that I have moved this post to the 1987-1996 F-series forum. Like the two users before me, this sounds like a classic case of vapor lock. Hope you find the information you are looking for.

The next time that you have this problem check to see if you have an adequate spark. It is possible that the ignition module is starting to go.
If the engine will fire when you spray a bit of starting fllud down the carb, then the problem is fuel delivery related.
