Started my 79 360 RC today that had been sitting for a couple of months. It idled fine for about 15 minutes and kept running smoothly after the 1st minute or so, then suddenly cut off after the 15 minutes. No sputter or anything. Just was running one second, dead the next. Tried restarting with no luck. Thought it might be flooded, so let it sit for 3 hours. Tried starting again with no luck. Starter turns the engine but no spark. I replaced the ballast resistor and waited another 2 hours. Still no luck. I can smell fuel, so guessing it is flooded again. Does this sound like an ignition coil problem? Or any other suggestions? Battery started getting weak, so I have it on a charger now. I don't mind replacing parts as many are originals and would be averting their future failure, but would like to start doing it in an order so that at least I know what is bad. I rerouted my fuel line away from the engine about 9 months ago to avoid heat causing Vapor lock, so don't think that is the problem. It is in the 70s today, and hood was up. So assuming heat isn't an issue.
