After a few weeks of closely paying attention to it trying to see if there is a pattern...seems to happen after it has been running a while, then I turn it off, and then come back to start it a while later (~1 hour). Cold start or turning off and starting again right away won't replicate the problem. I've heard twice now that it may be a solenoid... my bro-in-law says fuel system... and dealer thinks something in the electronic start... but until they duplicate the problem, are hesitant to start "fixing" things.
