I am not an expert...but...it sounds like the air vane governor is not working. In theory--the governor should give it more gas when your speed slows down. More gas gives it more power. I had a few problems with my Ultra until I understood the problem. New throttle springs fixed it. It should take a good small engine mechanic about 60 seconds to fix this. Sometimes a slight bend to the throttle bell-crank will clear it up.

We have run into this problem. It was as simple as the drive belt getting glazed and slipping. Just a note we put a lot of hours on are machines and we have found the Gates PowerRated 6838 belt works the best. Its a green belt. Good luck.
