But in this case it appears that the engine did just that.

It didn't stall, it quit. Airplane engines don't stall, airplane wings
stall, airplane engines quit. It's an english thing.

What happens when an auto engine stalls? I thought you could only
"stall" a car engine by applying a sudden load, as when popping the
clutch at low rpms. Jim L's list of definitions tends to support
that..

If that were the case, it would be impossible to stall an airplane
piston engine short of running the prop into the ground?

What happens when a turbine compressor "stalls"? Is there a critical
angle of attack for the turbine blades that's exceeded by running the
engine rpm too low or high for a given thrust? Or is backpressure the
culprit?
