I drove about 20 miles home from work got into a parking lot and the truck shut off I lost all power. We looked under the hood at fuses noticed that one was blown replaced it and without even turning it over just turning the key forward it blew again and then again.

You must have a dead short. Trace the wiring for bear spots.
