If i was going to guess I'd say he's got a pinched or plugged vent line on the fuel tank. It runs until the motor gets starved for fuel( because the tanks not venting and allowing fuel to flow out to the carb properly). If he stops and waits for a few minutes,or removes the gas cap, does the problem clear up only to re-appear 10 minutes later? Check the vent hose, if its twisted/pinched or clogged with mud or even spider webs it can cause that type of problem.

More detailed info is needed. What exactly do you mean by "bogs down"?

My dad has a polaris scrambler 400 4x4 and it bogs down after like 10 mins of riding. Do you know what the problem could be? were going riding tomorrow and he would like to know what it was or how to fix it.

Other than carb adjustments, there are 2 things that cause power loss in a 2-stroke.
1) Clogged Exhaust
2) Clogged Intake
