Hoover bagged wind tunnel 2 vacuum turns its self off after about 10 min. of normal vacuuming I can press the power button right away and the vacuum will turn back on and vacuum for sometime as long as 5 min before shutting back off other times it quits right away and I have to repress the power button again until it finally starts have cleaned every part of vacuum replaced bags etc. still shuts its self off what could be the cause

Check the inlet down by the brush roll to make sure it isn't clogged. If not and the hose isn't clogged, then probably the thermo protector (part #28382093) maybe bad. It is mounted near the motor. Could be motor Part #43576188. But I would suspect a clog in the inlet or hose, or the thermo protector has gone bad.

Possible that the switch is bad, part #40309033, take the handle off, then the tool compartment, then you can get to the switch, almost bet that one of the contacts is bad.

If the filters are ok, and there is no clog in the hose or dirt inlet down by the brushroll, then the motor protector is probably bad.

Replace the rocker switch inside the handle. Part #28161067, it's about $2.50.

My wife picked one up on the side of the road that someone had tossed. The power switch would not turn off. I took the two bolts out of the top part of the handle, and then removed the screws along the back. This will remove the required panels to access the On/Off switch. Once I found the actual on/off button, I found it to be frozen in the "ON" position. After manipulating it for a few minutes, I got the switch to work. This machine now operates great, and I now have a Hoover :)
