I have an MS661 that I bought on ebay (unknown history). I vaguely recall checking and finding it had the latest coil. I've ran about 30 tanks of gas through including 10 tanks of milling. Yesterday I was doing some milling vertically (for the first time). Halfway into the second slab it decided to quite. No spark. I switched to a different saw for an hour then tried the MS661. It started fine, And I milled with it for about 20 minutes and it quit again. And again after a rest it ran fine. I'm wondering if there is any electronic cut-off for temperature or oil level (I was cutting vertically) or any thing like that?
Thanks in advance.
Mike.
 
you might by now have a fair amount of saw dust and debris packed around the coil....clean it all out so some air can get to the coil and possibly clean the pull cord cover to improve the air flow andmight just solve your issue..

good luck
