OK so he ended up taking it to the shop and they found that when he got the body lift done it stretched his wires. All the wires are attatched to the frame, and when they lifted the body they didn't really notice it I guess. It was running fine for a while after he had it done, but then one day I guess the wires got stretched to the point of pulling out of the wiring harness. Well he just got it back yesterday with all new wires and harness, and he's back on the road. So for everyone doing a body lift be warned!
