It just turned off ? Need more info buddy.
That sounds like a WOT run that just stopped, and that, sounds like running lean in the HSN.
And if that be true, l would take a guess at a piston death if it wont run for more than a minute since.

Anyways if it starts and dies, try a different glow plug, do you run a hot plug ? Try a cold one !
And l dont mean beer ! LOL !

They can just turn off if they get WAY WAY WAY to hot, because with the expansion of the entire engine, fuel jets the lot, the tune is effected, gets leaner and leaner , until it cooks, and alloy can cool really fast, sometimes people dont notice that they have overheated.

Turn ya engine over by hand first see if it has any decent compression.
