Karl- I agree with Neil that it sounds like transmission, but I have not had that problem so no personal experience.
As long as we are onto other engine strangeness, my M4-30 dies routinely when shifting from neutral to reverse at minimum throttle unless I kick the rpm up a bit. I suspect it is a combination of the Max Prop and engine rpm set a bit low. I have to be very careful to come into slips slowly, but I always do that anyway.
