Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

My new (this season) Ariens 8526 works well and I love it.  But (you knew there was a 'but' coming up), twice now the motor has stopped for no apparent reason.  It just shuts down.  I then check the gas tank.  There is gas.  Both times I pushed it back to the garage and decided to try to start it.  Both times it started on the second pull and proceeded to run just fine while I finished the job.  Any ideas about whats happening?  As long as it restarts, I don't consider it a 'showstopper' type of problem.  But I would like to know why it shuts down. 

The fuel that is in the tank now is about a month old and it has stabilizer in it.

All input is appreciated.
