Car is Quiting

Took my 64 Fury out on Tuesday for the first time this year. It ran about 12 or so minutes and just quit. It had fuel and would crank over but no spark. I changed out a suspect ignition switch and it made a huge difference in how the car started, faster turn over and immediately started. Ran about 12 minutes and quit again..opened the bulkhead connector and found quite a bit of corrosion so I cleaned it and put a small amount of dielectric grease on it and put it back together but it still didn’t start. About 30 minutes later the car started right up so I put it in the garage before it quit again. I have tried another coil and ballast resistor that I had on hand, ignition is electronic.
I’m looking for ideas as to where to look, the car has its old car issues that I am working through such as windshield wipers that only go a few a few inches and then quit which is probably caused by corrosion in the switch or motor. Need some help on this one, I am no electric wiz at all.
Thanks all

Do you have a multimeter?
Check voltage in and out of ballast resistor and then at coil.
Sounds like the ballast or coil is getting hot then quitting until it cools.

You are not going to like my suggestion.

Of course, it is hard to say, but a guess would be a bad connection(s) and/or a bad ground(s). You said that you are working through corrosion issues. It may just be time to go through every electrical connection, clean and reconnect. Do the same for grounds. Most people overlook grounds and they are just as important as everything else.

Yes, doing what I suggest will be a royal pain in the butt. However, I feel it will likely cure many potential ills your car has. Even if it doesn't, it sounds like needed maintenance.

Good Luck!

I already changed out both the coil and ballast resistor, it made no change.

It makes far more sense than having a car you can’t enjoy.

Just because you changed them doesn't mean they are good.
Think about it...it quits when something gets hot and starts when it cools.
Coil, resistor, magnetic pickup or ignition module or wiring.

I have experienced what slap stick describes, but mine was an electronic ignition box that would work until it warmed up, then quit. Work until it warmed up, then quit. I think an ignition coil can do the same thing.

Also, a meter will help you A LOT. Check for loose/corroded/pinched wires along the ignition circuit (5-6 wires maybe?). If don't "see" any issues, you may have to drive around your neighborhood until it happens, then jump out of your car & re-check those 5-6 wires.
