The coil wire isn't a power feed. The computer sends a pulse to the power transistor, which sends a more powerful pulse to the coil, which sends a high voltage pulse to the cap. It arcs through the cap to whichever contact the cap is pointing at. If you suspect the cap is involved, check for spark from the coil wire to ground. If you don't have spark there, check the wiring/plugs on the transistor and coil. I would also check the wiring to the distributor--the sensor inside is how the computer knows the engine's position.

Might be worth sticking a fuel pressure gauge on it. See if the fuel pressure drops when the engine sputters out. I would also be curious to see if it'll fire on ether or carb cleaner when it won't fire on gas. If it runs on spray, but not otherwise, then you know you have a fuel issue. (You know for a fact that there's gas in it, right?) I'm not sure what connection the overheat would have to a fuel issue, though, or what the overheat would've damaged that would stall it out without some other obvious evidence of failure (losing coolant, white cloud out the tailpipe, schmoo under the oil cap, hellacious blow-by). Might also be worth pulling a spark plug after trying to run it. See if it's black or wet like it's getting too much fuel.

Water intrusion from the overheating to distributor or other electrical?
