Hard to say. I've seen a water pump impeller loose on its shaft so it doesn't pump coolant like it should. But if the engine is shutting down from excessive overheating, that's got to be hard on the internals. Pistons expanding in their bores, etc.
Does it sound different as it approaches the shut down? Smoke? Stutter? Lose power? Usually, an engine getting hot enough to seize up really gives noticeable symptoms; open the hood and it's
real hot, smells of burning oil, sounds of frying oil, steam out the radiator overflow, etc.
When you try to restart it immediately after it shuts down, does the starter spin the engine at normal speed? Or does it labor, as if the engine is seized up?
Has the engine been run low on oil? Coolant? Ever used a stop-leak product?
How far out of spec were the valves?
