Perhaps a NTS or prop failure.

I Probably will kick myself, but what is "NTS?"

On a TPE 331 series engine there is a "negative torque system" that senses
when the prop is trying to turn the engine (negative torque) and dumps oil
pressure in the prop dome which moves the blades towards feather. There are
several possible prop failures on a reversing prop all of which are much
worse than an engine failure.
