Question about Motorcycles
Your carburetor has multipule dirty passages. Its getting the right fuel air mixture at Idle but when you open it up it doesn't, which is why it dies. A through soaking of the carb in carb cleaner sould help or simply pull it off and have a shop clean it.

Just a hunch, had this happen to a bike of mine years ago, could be the piston rings are gettting ready to go(wore down). What happens is when the quad is cold the rings expand tight into the cylinder walls allowing it to get full compression and run ok. When it heats up they shrink allowing the slightest amount of give which in turn will cause you problems similar to what your describing.

ALWAYS have a fire extinguisher on hand when working on carburetors.
Open the petcock, (gas valve), and drain 1/2 cup of gas from the tank. Did the fuel flow freely? Is there any water or trash in the cup?
Drain the carburetor. There should be a screw on the lower right side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Check the float height. The fuel level in the bowl may be low. Bend the tang (in the center of the float) downward to raise the fuel level. EASY, a little bend goes along way. Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine.

Even though you probably don't have that many miles on the bike, or if you do have a lot riding time on it, it sounds to me like you need a valve adjustment. That's a high reving bike for that engine that works pretty hard so you might have 1 - 3 loose valves.
