The belt looses it tensile strength (tightness) over time. But it's the part about funny sounds and shutting down that concerns me. If it smells like a tire fire then it's the belt if it smells like plastic and burned hair then the motor has a bad field or armature. Probably one of the carbon brushes got hung up and burned a segment in the armature.
