These motors have a fuse incorporated in the field winding and it sounds like that blew. These motors sometimes overheat at the front bearing and the bearing will melt into the plastic housing. This will cause the fuse to blow. It sounds like that's your problem. You can remove the motor by removing the three screws on the bottom of the powerhead and then check the front bearing for any bubbling or blistering in the plastic housing. The shaft of the motor should turn easily.

What has worked for me on this vacuum is once the handle is off and the on-off switch is visible, work it back and forth manually. Mine was very stiff and it did not get any better. I went to radio shack and bought a spray can of Control/Contact Cleaner and Lubricant. It comes with a small piece of tubing. I put the tube into the top edge of the switch and pushed the button FOR A FRACTION OF A SECOND and then did the bottom edge of the switch. I worked the switch manually a couple of times. I repeated the spraying one more time and the rocking. I put it all back together and has been working fine for me. This stuff is made for electrical contacts... HOWEVER, use it very very sparingly!!! ALSO, a new can has a bit of pressure so watch out that you don't blow some back at you. JOE

SOURCE: Belt replacement
No belt- it is motor driven. what happens to these if the rollers get stuck(by- say, a Lego® or something) is the roller itself has an insert which will break, requiring roller replacement.
simple fix, but costs a little more than a belt. remove two screws holding the roller cover, accessible by flipping the vac over. then figure out which roller is broken, and remove the 2 outer screws on that side. pull the outer bearing cup assembly straight out to remove the rollers.
I have found the rollers as cheap as $3.50 ea/ for generic replacements. Also I reckon any Vac shop would have them on hand.

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.
