Stick? Automatic?

How much current goes to the starter under each condition?
About the same or much more or less under the fault condition?

Can you reproduce the problem with an unpressurized cooling system?
(Loosen the radiator cap before starting?)

If you remove the sparkplugs after the failure, does the engine spin
up at about the right RPM or is it still bogged down, indicating
perhaps a main bearing problem?

Oil look ok? Not 'creamy' as if water has gotten in?

Sick injector(s) sticking open when heated?
