I never flew an piston engine that will continue to run at idle with a
feathered prop... Way too much load...

With the propeller feathering at low/no rpm, it must be
inspected/repaired. Then the first step in diagnosing a strange
"governor" problem is ensuring that the proper amount of engine oil is
present at the governor pad. The tooling to accomplish this also makes
it easy to check the prop oil supply path from the other passage at
the governor pad through the front main bearing to the prop galley in
the crankshaft.

So how do you explain the engine stalling in addition to the feathering?
