Bill, I'd guess zero-g could be a possible cause of the power loss. It is a gravity fed fuel system, after all. In addition, we've seen a few instances in which the extreme nose up attitude of a full power stall caused short term power loss. I'm guessing that this is because there's insufficient gravity "head" pressure. As the nose and carb get higher and higher relative to the nose tank, the fuel pressure gets lower and lower - all at a time when you are at a high power setting. As long as you are not just above the ground, trying to clear the trees, it's just a pucker-inducing "interesting" event. May you live in (not too) interesting times!
