I'm assuming you put fresh fuel in it. I'm no nitro guy just getting into it, but this sounds familiar to how my 87 ramcharger is that I'm fixing up. Its got 4yr old fuel in the tank and the choke doesnt work, so until i get it warm from 10 minutes of running the 360 will just die at idle. I'm assuming the airfilter is off? If not something coulda got clogged in that, this will flood an carbed motor.
