Been having an issue for a few years now. It happens on and off.

I have a 1969 C20 with a 350 5.7l. I'm having an issue with the truck not starting somewhat randomly. Always seems to happen after I've been driving a bit and I'll stop at a store and when I come back it doesn't start. Doesn't happen after sitting over night or after working a full shift, just when I come back to it 20 mins later.

When it doesn't start, there is nothing. Lights come on, music, voltage is good. It does nothing. No clicking no nothing. I have to jump start it to get it to start and then it will start after that again just fine until another random day. Troubleshooting has been hard because I can't get it to recreate the issue at home.

I have replaced the battery, starter, alternator, negative battery cable and clamp, distributor, plugs, wires, ignition switch, neutral safety switch. I've tested and cleaned grounds and wiggled wires...idk what else to do other than replace the starter and battery again.

Any ideas? Thank you!
