Could clutch be on its way it's fine on flat ground

 

Clutch or compression. A plugged pipe can do it too till it plugs worse.

 

Any other ideas just loses power up steep hills might be because I've been riding it weigh 200 pounds

 

So you've checked the clutchs and compression?
IMO 200 pounds isn't a big problem.
I suspect a roller problem but I'd check the compression.

 

Will check roller as I'm removing two next week seems to be running fine today if it get wet can belt slip

 

Yes,belt will slip if it gets wet.

 

After knowing that (water), I think that after clutch maintenance, all will be fine.

 

Yes it got wet on Sunday I bet that's the prob as it seems ok now

 

probably a wet belt, i removed my oil injection pump once and never plugged the hole, and water got into the hole where the pump goes, it was wet FOREVER lol, i figured it would dry out after a few days, but nope, had to disassemble and dry everything and clean it all. now i cover the pump hole
