I would clean all the fuse contacts and replace the fuses especially #1. Clean the contacts on the ignition module (right side inside fender area) and small pickup plug on the distributor.
Also check for loose/dirty grounds on engine harnesses.
Scotch brite pad works well for cleaning grounds. Tune-up grease will help protect from further corrosion.
Also possible water in gas.
I think ignition is more likely than fuel in this instance.
