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

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.

You didn't specifiy that it was the same engine all the time, but I'll
presume that to be the case. IIRC, feathering is usually brought about on
those props by lack of oil pressure, right? So it is either a lack, or a
perceived lack of pressure.

Actually, I'm more fascinated by the fact that you took off and flew around
not once, but apparently at least twice, in a craft with a prop that was
inexplicably self-feathering. Hmmm...

"Air Adventure" is right. What were you doing flying an aircraft that had
an obvious engine/prop problem? This should be looked at by a competent
mechanic before flying again.

Three MAJOR issues:

1) Prop feathering - it is out of your control.
2) Engine stalling
3) What seems like very high oil temperature after landing.

You could have a real major problem there and by flying you could very well
be compounding it. What if there is an oil blockage? There could be parts
of the engine not getting oil and damage occurring to those parts (this
could account for the high oil temp).

Hey, I'm no A&P but this machine is crying out for help.

I forgot to put it in but the mechanic looked at it and brang up the idle on
the right engine and put more oil in the engine and said go fly. He's Just
trouble shooting right now. and the same thing happened. It happened once
before about 2 months ago but then it stopped.
