well it started a while ago...when i drive it around for about 5-10 minutes all the sudden the engine dies....i first thought the needle and seat were bad or the float was sticking but they all checked out ok.. any suggestion what it might be?

 

New spark plug or disconnect the limeter.

 

Does it seem like it's running out of gas? If it does, when it starts to die, quickly open your gas cap. If it keeps running you've got a kinked or plugged vent line. This happens a lot.
