The correct belt is a 38528035. If the belt does not have this number printed on it, it is a generic belt and probably the wrong one. The pulley on the transmission is "convex" because this pulley design keeps the belt running in the middle. (a belt will always try to "climb up a hill") If the motor shaft and the pulley are not aligned properly, the belt will constantly throw off. This can be a result of a bad motor mount (located inside the motor compartment.) The motor shaft end has a rubber cover that absorbs vibration and keeps the motor positioned squarely. The handle could also be loose on the pivot. It is held down by two metal clamps that screw securely to the bottom, holding the handle on to the base and allowing for the handle to pivot backwards. This problem can be difficult to diagnose and I have had many in my shop for repair. It takes a seasoned and experienced repairman to find a solution to this problem, in most cases. The disadvantage I have here is that I cannot see your machines to inspect all the various things that effect the belt alignment. I hope that some of this information will help.

If the low voltage wires are hooked up to it, then you probably have a stuck relay inside the cannister. It could also be the switch in the hose handle.

I have a Windtunnel S3765 with the same problem - and it has very little use so I'm confident it isn't wear. I find that the wheels do not raise the agitator brush sufficiently high to reduce the drag caused by excessive contact with the carpet. If I raise the front a bit the brush spins as it should. It also works if I take the housing apart and use it without ..... but this is tricky.
Unfortunately I haven't figured out a way to hold it up efficiently. I am toying with afixing something to the bottom of the housing to raise the front enough to give the brush a little more room.

SOURCE: Hoover Windtunnel shuts off
I found the following solution on this website. I have searched for hours and finally found this solution, it works! I HAD the same problem after cleaning the filter mentioned below, it is now working like it was new.
yes this machine has a thermal protector in it to shut off the machine if it gets to hot, this is normal. if there is no clogs in the hoses or in the machine then you will need to wash the filter at the top of the machine. you will have to remove the dirt cup and at the top you should see a half moon orange, well inside of this piece is the washable filter, clean and let it dry completly before putting back into machine. if this gets dirty and has not been cleaned, you can lose alot of suction. in some cases if this filter is not cleaned it can cause the machine to overheat so bad that it can damage the motor.
