Unexpected engine failure (shut down) 1994 Ford 460 V8

Sounds like you have a fuel pump problem. You were running 60 mph and shutdown with no slowdown or cool off period (pulling in gas station or parking). Oil and engine at temp at this point it will get hotter for about 15-30 minutes then start cooling down. Check all grounds and change pump and filters problem should be corrected. While you have the pump out drain and wipe out fuel tank. I have seen the heating problem several times. I have checked several vehicles with a thermal camera and infrared thermometer.
