The grounds definitely need some attention in the engine bay. I've messed with a lot of wiring for mods, so that seems like a reasonable fix. It's easy enough to clean mounting points or add more ground wires (yes, I did that on an Evo as a tuner-mod a while back). If it's clearly corroded at the tank / sending unit, that may be a give-away.

We were in the thick of the heat/drought here in KC until Isaac dumped enough rain to fill things back up (most of the corn crops not surviving) so it may have been the last straw in it's long, hard life of empty fills and extreme temps. I think the rear seat might have to come out and then a metal cover with a few screws expose the fuel components and it's good to go for replacement.
Looking at the big picture, there may be a fuel delivery and electrical problem (possibly vacuum to fine-tune). It may not have been enough to throw a lean-condition code or emissions fault when the ignition was in flux. We'll see.
Thanks again to everyone for the advice! Like with lots of us here, I learn as I go with vehicle repair and it's appreciated. The next run is 52 miles later this week. It may not happen then, but at least I'm armed with the info to attack it when it does.
Take it Easy...
