Engine runs fine but seems to seize after wot

Im having trouble incorporating the 3 hr to normal restart thing into the above theory.
-I have seen it where a hot starter would not spin because the armature would magnetically stick to the field coil assy, due to excess clearance in the end bushing.Upon diss-assembly the drag marks could clearly be seen, both on the armature and on the coil. Just FYI.
