Prop Feathers and Engine Shuts down after landing????????

This is only a guess but may make some sense. Some CS props will go full
pitch if oil pressure is lost, others will to to minimum pitch with no oil
pressure. You said that the oil temperature was high. (an indication of low
oil level). Also how is the oil pressure just before it shuts down? Being
at idle already, full pitch could make enough drag to stall the engine.
OTOH, if the engine stalled first, the lack of oil pressure would cause the
prop to feather too. Make sure the oil is the right viscosity too. In planes
with oil inversion systems, it's important that you have the type of prop
that goes to full pitch because the pressure drop during the transition to
inverted would cause an engine overspeed if it was the type that went to
minimum pitch. Not that yours has an inversion system, but it's nice to know
which prop you have. Let me know how you make out, I will be reading the
other replies too but am curious to answer to your problem.

Today I was flying my Twin Comanche PA30 everything was great until after
landing. Once I had the wheels on the ground I pulled the power back to
idle,
about three seconds or so after I pulled the power back the prop feathered
and
the engine shut down. I let the engine cool down for about 30 min then
started
the engine right up. Everything was running great. So I took off and
flew
around for a while then came back to land, this time after I landed I
put
the power back up to 1500 rpm, the oil temp was right below redline the
oil
was at 50psi then the prop feathered and the engine shut down again. This
also
happened to me yesterday. Every time I land the prop feathers and the
engine
shuts down . Everythings always great until after landing. I only have
40
hours on the engine. Could anyone please help me out? Has this ever
happened
to anyone before? Does anyone have any ideas on what it could be thanks
for
everyone's help.
