OK, got my new mach from the muffler shop today, runs great, but after about 15 mins or so, all of a sudden no power lots of sputtering, full throatle nothing, off the throatle kinda runs, anyways it stalls, I leave it for about 2 mins, starts no problems go for about 2 mins, starts acting up again, did this five times until I got home, it stalls in driveway, I start it up varoom back to life. What the hell could that be:scratchchin

Sounds like a coil breaking down with heat.
When it stalls and won't start check for spark.

well thats the problem it starts up again and its a new mds ignition, i'm thinking when I have full throatle it dies, but when I back off the throatle it kinda comes back to life it would be a fuel issue, the ignition is not controlled by the throatle or is it:scratchchin

is it tuned? Timming might be off, floats not set?
