Ok guys... in 63 new yorker I was on my way to work this morning.. pulled up to stop sign and engine died.. not a sputter die.. but just cut off. Radio and defroster still running. I put in park and refired it... started..for 20 seconds.. died again.. same deal. Restarted again.. seemed ok.. drove about 2 blocks and died again. Refired and turned around and headed home. It stayed running all the way. Stock Points ignition. Any ideas?
