Heat related is usually electronics, but not allways.
We really should do a proper diagnostic.
Next time it quits check for power to the coil. Then see if the distributor and module pulse that power while cranking. If it does we are looking at a relay or such in the injection (we hope). If it does not pass, the pickup coil in the the distributor is the last thing you havent changed.

NOW OVER ONE YEAR AND 5000 MILES WITHOUT ANY PROBLEM. I am confident the following solve the earlier 460 stalling, stuttering, lack of power issues. These engines were made pre ethanol and were intended to run off of 100% gasoline. I have listed the following that has worked for me.
1. Stay away from Interstate truck stops for fuel.
2.I use the following fuels ONLY and in order of my experience with performance:
a.BP High Test. Preferred
b.High test Shell, Phillips 66, Sunoco
c.EVERY tank use SEAFOAM = TO # GALLONS FILLED, 1 bottle red label ISO HEET. THIS IS CHEAPER THAN ROAD SERVICE
I ALSO DID THE FOLLOWING MECHANICALS,
New better aftermarket in tank fuel pump and filter.
New ECM and Coil.
Wrapped the fuel line and fuel rail with insulation foil.
Installed an in line cooler (small transmission type) in the return line to the tank.
Banks cold air intake.
