My mechanic is thinking thermostat or distributor since it also would not re-start at a drive through. Obviously I avoid idling.
The engine is being gently cleaned and I'm changing the oil every 2,000 miles.
It had a recent tune up, has new tires set for current weather conditions.

I've been using regular gas (10% ethanol), from the same Shell station.
Until the past cold snap, the weather was mild with little wind.
Anything you can suggest to be more consistent? What might explain this?
I Also have a 97 HX and have some widely (-5, 6) varying mpgs
In my experience over the last 7 years, colder temperatures and winter gasoline (they start selling it in November around northern Arizona) contribute to about a 7% reduction in fuel economy compared to warm weather and summer gasoline. It's quite noticeable in my car's fuel log graph.
