Default 2K Foreman 400 runs great, then dies. HELP

I have a 2000 Honda Foreman that will run for 15 to 20 min then it just shuts down like the gas has been turned off. Then in about 10 min it will start again a run for another 15 to 20 min and shuts down again.

I've had the carb off twice, once with just the bowl off, cleaned the jets I could get to. It ran great for most of the day then started doing the samething again. So I took the carb off and completely tore it apart, soaked it in carb cleaner, sprayed carb cleaner in all the jets, lines, carb orifices, the primer, float....everything Then I put in an in-line fuel filter from the tank to the carb. Ran for 15 to 20 mins samething.

The only other thing I know to do is to put a new carb kit on it or buy a new carb. I just want to ensure that would fix it, but not confident it will. It just seems like it's something simple because it stops like its not getting gas, but I am out of my mind trying to understand why this would be happening. When it runs it runs great, then just dies.

Just not sure what to do next! Any suggestions in next step?

Let me know if that works. Mine does the same thing and I did everything you have but one of the valve nuts truns in the tank. I did blow through the valve today and got a chunk of blue foam ?

Check the vent on the gas cap. If plugged, it will act like this.

Sounds like a vacuum/vent problem

Try running it with the gas cap off and see if it does it.

If that works, what does that now mean?

It would mean the vent tube for the gas tank is pinched or plugged
