Very likely it's the cord at the nozzle neck. These cords flex when you vacuum and they often break internally where the cord goes into the neck. Turn the vacuum on and wiggle the cord at the powerhead and see if the powerhead comes on and off. If this happens, then you will have to replace the cord.
On some of the early models, the receptacle in the hose, where it plugs into the top of the wands, will break away from the plastic pins it sits in, and the receptacle will slide back into the handle, which means that it will not plug into the powerhead connection when you connect the hose. You can check this by looking at the end of the hose and observing if the receptacle is sitting flush with the opening it sits in. If it is pushed back, it will not make a complete connection with the powerhead cord that is sitting at the top of the wands.

Mine does the same thing. There is no suction. I found that there is a door that opens when you tilt the handle in the down possition. I think there should be a spring in place so it can open. Until I find a replacement spring I have to open the door manually throught the opening under the light.

Check with the manufacturer. I have always had good response from Hoover.

You probably need to change the belts. Here are the belts you need and the manual:
