this is drivin me to drink!!!! I did all the pre run goodies, checked for gelpak, changed oil and sparkplug, tightened all connections, no kinks in the fuel line, good flow and spark....you caN START THIS THING COLD, IT FIRES RIGHT UP, LEFT IT IDLEING FOR 1/2 HR, STILL PERFECT, took it out to go riding, 10 min of soft riding, half throttle type stuff, he is still learning, and it stalls suddenly and will not restart...if you put the choke to full on and give it a bit of gas it will fire up, but only for about 30 seconds or till you let off the throttle.....has done this 4 times in 3 days....first day it went about 45 min, second and third about 20 min, now 10 min........HELP!!! the look on my kids face is killin me...he REALLY wants to ride this thing

 

UPDATE!!!!!
after messin around some more, I found 2 things; a poor conectivity on the tether at the back of the quad (solution: undo it at the wiring harness and remove) and the big one....the vent tube to the gas tank...its not blocked, but as soon as I attachit, I can set a timer to the machine shutting off in 10 min or so....left it of today, and we went out for 2.5 hrs without a single problem......

 

glad you got it fixed, soo should all gas tank vent tubes be blocked, my mini 110 isn't and some times displays similer problems...
