Crank up and die

Hello everyone. 68, stock 289, 3 speed, 4100 autolite.  It cranks up but dies, as if you turn the key off. Crank up and die. Until it catches and stays running. This has become more frequent and more tries before it catches. I checked the points and coil, they're getting spark. I put it back together it starts working again. I've had this happen to me before, but the problem just went away. Now it came back. First time it happened I unplug the connection under the steering column, eight or nine wire, and plugged it back up. So it might be ignition switch?
Thanks for your Help!

Re: Crank up and die

Sounds like you need to be tracing out the run circuit.

Re: Crank up and die

Yup, what John said.   Sounds like you may have a bad Ign. Switch or a crappy connection between the pink Ign. wire and the firewall connector.  Or possibly a bad connection between the pink wire and the pigtail at the Ign. Switch.  Or maybe between the firewall connector and the coil.  Since it eventually "catches" I betting on a bad Ign. Switch.
The coil gets power from the "I" terminal of the solenoid during start but that drops out as soon as the key returns to RUN.

Re: Crank up and die

Thanks for all the help! I jumper wired the coil then jumped the starter solenoid. It cranked up and stayed running every time. So I figured it was and bought a new switch. But being old fashioned, when I pulled the wiring from the ignition switch I cleaned those terminals, cleaned female wiring harness with toothpick, put it back together. LOL It's cranked and stayed running 10 times in a row now. I'll keep the switch in the trunk. It is the one you replace your original key in.
Dang thang made me nervous at the convenience store so I reached out to the pros! Thank you everyone!
