Bogging and loss of power out of nowhere

Hello guys so I have an 07 Polaris Sportsman 700 twin EFI and Ive been noticing this lately but here’s the problem. So I can ride the atv perfectly fine for a good amount of time and then out of nowhere it just loses power. At first I looked into the gas tank and there was gas and it was pretty low so I decided to go back to the truck and while going back it would gain its power and lose again at the same time. Can anyone please help me with this problem feels like running on 1 cylinder and if I let it sit for a day its perfectly fine.
