Carson - I had a problem like this on my '72 once. It would skip a beat just
once in awhile and then one day it just completely quit. It started up but a
few weeks later it quit again. It turned out to be corrosion between the
baseplate in the distributor (where the points are mounted) and the small
aluminum mounting block beneath it. This is where the circuit gets it's
ground.

Of course I didn't have any thermal switches or relays (I don't know what
all that's about). I'd suggest you start by jumping a wire across all that
crap and see if your basic ignition circuit is working okay.
