Okay, I've got a '65 with a 351W. She starts just fine, runs fine, and then about 10 minutes in, it acts like it's out of power (gas or electrical) . . . but isn't. When I try to restart, the starter won't turn over but once, BUT when I let off the key, it turns fast once (not enough to start). All the other power stuff works FINE, and the electric fuel pump is running, too. Now, let it sit 2 or 3 hours, poop, no problems. It's not vapor lock. I'm thinking oddball starter solenoid issue. What say ye professionals?
