I finally got my truck back on the road and it was runnning great (just hauled 4 tons of gravel home with it, with out a hitch!) then my brother borrows the truck and it just dies. He says he just pulled it out of gear to coast onto an on-ramp, and when he put it back in gear it had stalled. it won't turn over, the battery is charged, the windows and fan work with the ignition on but the radio and motor does not. I don't even know where to start with that terrible mess of wires under the dash. I suspect it's a fuse or relay somewhere, but really it could be anything. Anyone have any ideas?

 

Probably one of the fusible links just to the rear of the battery. Look for crispy looking wires.
