Sounds like the beginning of the end for the clutches. Or could be a slightly clogged jet. Try Sea Foam in the tank, and inspect the clutch pac

Any updates on this? Mine feels like it slips. Only does it in high gear when under load, not low gear. It's a 2008.

Yeah! I know it's long shot. Was hoping to get lucky lol. I think it's the belt though. It had been sitting for a few years before I bought it and got it running. Haven't looked yet, but it may be dry rotted a little.
