Does it die as you twist the throttle or after riding it a short distance? I know its seems a silly suggestion but are you turning the petcock in the correct direction? Try the twister in all of the setting positions and see if a different one fixes the problem. Keep in mind if it dies on a throttle twist it might not be fuel causing the problem.

Use heavy duty SAE 80W-90 gear oil

Engine oil does work but the oil will not last as long nor will it protect the bearing's/gear's as well as gear oil. Thick dif oil can work to.
Also the gear box is should be sealed.

Check oil level capacity, to ensure in specs. Check spark plugs, ensure its clean and correct plug for your quad.the only other could be is ign coil breaking down when warm. Check fire at plug when this happens. First ensure oil level is correct. Make sure your electric fan is on when bike is warmed up.
