Ground and power connectors/wires all in good condition.

If you source the ignition key-on power from the ignition switch, perhaps try a jumper and temporarily power it from a good known source. Ignition switch could be on the fritz...

Easy enough to do a resistance test on the wires...

I think i have in narrowed down to the distributor. It has a bad rev limit dip switch and the center conductor is a little worn. Swapping in a new motor as we speak so i'm going to stop troubleshooting.

Thanks for the suggestions!
