Don't just throw money and parts at your truck. My 93 did the same thing and my issue was the distributor module. The distributor module is the little piece under the distributor cap, below the rotor that is screwed to the base with a couple of screws and has approx. 3-4 wires connected to it. Anyway, Some auto parts stores can check these off of the vehicle. You might want to take yours off and have it checked before buying a new one, once you buy a new one they normally won't refund your money. Be very careful as the connectors can be very brittle.

The auto parts stores will tell you that the distributor module will either work or they won't and the temp has nothing to do with it. That is Bull***t, my 93 did it to me twice exactly as you described, only when hot, once it cooled off it started right up.
