Several days ago, my truck died while cruising at 60mph. There was no warning, pops, knocks, or clunks. The rpms dropped to idle then a few seconds later dropped to zero. Truck had full power until it died. Fuel pressure is good. Only throwing the p1693 code.I believe it to be a ground issue. The truck radio lost memory after sitting overnight and turned the am radio on. I'm looking for wire diagrams or someone who has maybe had a similar issue or any ideas. Anything will help!

Check grid heater connections below drivers side battery. They're big cables with nuts that are probably loose. 

 

Mine were and my truck would randamly die going down the rd. Pull restart like nothing happened.  My radio also loosening memory
