I am leaning towards the possibility of it being 3 possible contributing problems:
1. The rear end this should be an easy to diagnose and simple repair (at a shop). Not relevant to the electrical issues in any way.
2. The shut down while driving may be fuel pump related, unrelated to the failure to start problem. I have read there is a possibility of two fuel pumps on the high capacity tank (39 gallons). Both times it **** down the truck had be running for an extended period. The first time it shut down while driving it had been running for about 16 hours, and the second time about 7 hours.
3. The random failure to start and resetting of the radio clock??? I really have no idea. Now I am wondering if it is possible to have an intermittent short in the battery.
Hopefully a shop near me that comes highly recommended can diagnose and fix it. Until then, I am blessed to be able to surrvive while it sits parked in the driveway.
