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
Try turning the ignition on and waiting a few seconds, before cranking, on your hot restart to see if that helps. If the fuel rail is not holding pressure, the ignition on and wait a few seconds will allow the fuel pressure to get up to specs and should make a significant difference. If not then look elsewhere, but you can't beat the price on the diagnosis-free. Nissans had a fuel pump check valve that was available separately for around 10 bucks. Not sure about that era Honda.
