Can be a ecm possibly going bad especially if it’s never been replaced.

Start the truck, open hood, smack ECM with screwdriver handle or rubber mallet... Might want to have someone in the cab to see what happens. But, mine did the same and left me stranded on the side of the road when it shut the truck down. One Million miles and the original ECM, it is time.

also check for bad grounds

And battery connections. The main ecm feed comes directly off the batteries. It one of the several small wires that are connected directly to the battery lugs

Smacked ecm nothing happened checked plugs on ecm nothing checked battery connections nothing

The reseting of the trip meter is what has me stumped could it be wires going to speed sensor
