I've seen posts about cold start stalling and older models stalling due to software problem, however I haven't seen any post about this problem. Wondering if anyone has any insight...

I've got an '06 MC with CVT, only 200 miles on it. Today after driving 20-30 miles of highway, I came to a bridge toll booth, stopped, and stalled. Caught me by surprise. I put the vehicle in park, turned the ignition, and it started up again, no problem.

(Other details: It wasn't hot or cold today (60 degrees today in Cal). I had just filled up my tank (for the 1st time!) w/ 11+ gallons of premium from 76.)

But should I be concerned? Anyone experience this? Is a service visit in order?
