Sounds funny/shutting off after few minutes

\015 I have a Bissell LiftOff Revolution Pet Vac that is about 2 years old. All of a sudden it only works in the floor mode (won’t turn on in wand mode) It also sounds funny, if I do get it turned on, it usually only lasts a minute or two before shutting itself off. I don’t see any clogs and the canister is not full. Any suggestions?\015 – Bissell LiftOff Revolution Pet Vac 37602 Vacuum
