Eventually I traced the problem to a crappy splice in the main power wire coming from the battery, via the small distribution block on the passenger fender, to the fuse box. I soldered and shrink wrapped the faulty splice and was back in business.

Years later I had a similar problem in my Suburban. I traced it back to a loose bulkhead on the backside of the fusebox.
Nah, it's fine. I've got 50/50 money on fuel or electric at this point.

How did you determine it was a bad splice? Jiggle the cables? I've been doing that and I haven't noticed any odd behavior. I may still not be jiggling the right one though.
