I had the same problem, no oil leaks until I shut it down then a puddle. It turns out that any air (vacuum) leak will not keep the scavenge pump from pulling all the oil out of the tank but it will drain back after you shut down. My air leak was where the oil line goes into the pump at the 90 degree bend. It was rubbing on the exhaust heat shield and wore a hole in the brass pipe.

You will likely find a leak somewhere.
