Hi All- I have a 2016 Mule 4010 (model: KAF 620V). I am having an issue since overloading the payload a couple days ago (yes I'm a dummy). I live on a very hilly property and I was trying to move some large oak rounds for firewood splitting. I put WAY too much wood in the bed and when I started driving, it sputtered, kicked out of gear, and then cut out. I unloaded all the weight and started it again - appeared to be running fine when idling and/or driving on flat ground at slow speed. But when try to go fast or uphill, the RPM's rev high and it sounds like the motor is fine, but it has ZERO speed or power at all (literally creeps uphill at like 2-3 mph and won' go faster or take any weight), and has no power at all.

Other info: 3 weeks ago I did a belt replacement. So I was worried I perhaps screwed that up somehow. But I just opened the clutch housing to check and the belt and clutch appear to be working just fine.... sooo.....

Any ideas what I screwed up by overloading payload and immediately trying to drive uphill? Any tips would be greatly appreciated!
