Either the prop governor, or the piston in the hub are going to hell in a
handbasket... The engine 'stalls' when the prop goes into feather - I
doubt
that there is an engine problem... Sending the governor out for overhual
immediately, would be my inclination...


Could also be the collar on the crankshaft where the oil gets injected
to drive the prop. There was an article on this recently in "Light Plane
Maintenance", but I can't put my hands on it right now. If the tolerance
is a bit out, there could be a pressure loss sufficient to cause the prop
to feather.
