I am 85% certain a new Moyer coil will get you fired right up again. Would guess that the electronic ignition stressed the old coil over a multi-hour run, and burnt it out. Sometimes when that happens, but apparently not in your case, the coil simply overheats and will run the engine again for a while when it cools down. But in those situations it is definitely failing.

It's also possible that the little wire in the electronic ignition that runs under the cap chafed through and grounded out. You'll be pleased when you remove the two screws holding the cap onto the distributor - it's easy to look at, and not very complicated under there. Just make sure that little wire doesn't get crimped when you put the cap back on. There's a notch for it to fit into.

Other more distant possibilities: the rotor cracked and isn't turning properly, the cap has too much carbon built up around the contacts to be effective, the electronic ignition itself failed (highly unlikely).

What I really recommend you do is buy a new coil, cap, and rotor from Moyer and replace them all. It's a ten-minute fix, plus the time you spend admiring it as you assemble/reassemble it, which could be considerable. Strongly suggest you carefully label where each plug wire goes onto the new cap, by looking at the old cap, before you pull those wires off the old cap.
