Does it have a lot of hours on it? If it is slowly loosing more and more power as it gets hotter it may need some new rings or possibly a cylinder bore and new piston/rings. It could be improper jetting...if what you are saying is that it runs different at different altitudes. Try doing a compression test when the engine is cold then do one when it is hot and see if there is a substantial difference. You could try cleaning your carb and air filter to see if that helps also.

Good luck with your quad!
