My son's was driving his 2002 F350 Diesel 4x4 pickup truck with the 7.3 engine after getting the transmission over hauled when it just quite running. He tried starting it and it spun over but wouldn't start. The battery light on the dash was blinking. He soon ran both of the battries down and didn't have any lights including dash lights. I pulled him home. Next morning he came out and it started right up and ran fine. Shut it off and tried it again and nothing again, waited a while and it worked just fine again.
Any suggestions on fixing it?
