1990 LA 360 stops running when hot (help please)

I had an 89 Daytona Shelby that on a road trip to DC and back (800 mile round trip) cut off on us on the interstate and would not restart. Had it towed to a shop, stayed overnight at a motel, shop called in the am and said it was fixed, that it was the ignition pickup in the distributor. Collected the car and off we went on home but I had my doubts if that was the problem as those things either work or they don’t. An ignition coil perhaps but not the pickup. Anyway, about a 1/2 hour into the drive it did the same thing. Ended up renting a car to get home, drove back up with a dolly to get the car.

Back at home I was able to systematically diagnose the issue. Turns out it was the electric fuel pump in the tank. It would get hot from running and seize up thus killing the engine. Replaced that and was good to go.

Very hard to replicate unless it gets hot but after it dies again, immediately see if you can hear the pump cycle on with the key on run.
