    Cleaning your air filter is a good start. Sounds to me like you have some blockage in your carb and it's getting starved for fuel. Check your jets and make sure there is no blockage and make sure that the float is not sticking.

    BTW: What kind of quad is it? Have you done any work to it recently?
