sounds like rich mixture, to much gas not enough air. when was the air filter last changed, has anybody been messing with the carbs. Check the spark plug once its warmed up and it starts dieing, if its black and sooty its a good indication its too rich.

Not much but it gives u a start.

things i would check are mixture and also the needle position as mid to wide open throttle are controlled by the needle, needle jet and main jet. Also see if any air jets are blocked.
