The coil is probably faulty. It runs until hot then cuts out, start again then cuts out until you cannot start it. After it cools down for about 30 mins it starts fine. Get a new coil pack and it`ll probably run fine.

I have a 42cc Homelight that does the same thing. I guess it's a cheap saw thing! I bought a Stihl 031 and haven't had another issue.
