Without actually seeing it, I would check the battery.

Check the positive and negative battery cables....when wires heat up they create more resistance. When a bad cable heats up...it creates a lot of resistance, enough to loose almost all the power. If you have not replaced them and they're original, than replace them...it's pretty easy.

Both cables go down between the engine and the fenderwell. The ground is bolted to the frame and bolted to the engine block, the positive wire goes down to the starter, another lead to the alternator.

After you check the terminals, load test the battery. A quick check is to start the engine with the headlights on, if the lights dim way down the battery is dead.
