Fuel Pump Cavitation.
I have no experience of the engine/prop installations mentioned here and am somewhat reluctant to make a comment, except to say that any aeroplane on which I have operated and which was fitted with a featherable propeller has always been able to be shut-down and, if required, able to be restarted regardless of whether it was a "Precautionary" shutdown or an "Emergency" shutdown without detriment to any component.
