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...

Actually, it may just be a bad idle mixture setting. My engine when hot used
to stall at idle (frequently rolling out with the throttle at idle). I didn't have a twin,
but I can imagine that the prop would feather during such a sequence in a twin.
