What Causes this ?
 
I have come accross a problem with a buggy motor that has me a little confused. After a few minutes of running the idle drops to a point where it will flame out on corners or pit stops, etc. If the idle is set correctly when the motor is hot it seems to run fine . After letting the motor cool down and restarting it idles really high.

The tune seems to be fine, and the motor doesn't overheat or do anything strange apart from this.

What type of engine are you running?? Check your fuel line and pressure line, even make the pressure line longer. It may be air leak related not fuel related....
