Need help with 2008 RMK 700 rough idle and bogging

Seabeck, Wa.
This sled has been running perfect since it was new then last week it started bogging at low end rpm and then started idling rough. Then when you start it it will idle fine for a minute then slowly increase rpm then start running rough and die. I changed the fuel filter, air intake boot between throttle body and reeds was separated so I replaced that and inspected Reed's and thought that was it for sure but started it up and it's doing the exact same thing. Only run non ethanol premium in them. Anyone have any idea what's wrong, next step is to take it to the shop if I can't resolve it quickly.
