Even at 5 or 10 miles per hour, until I came to a COMPLETE stop, the ICE would not shut off.
Any ideas from experienced owners?

it could be that the ecu thinks that the catalytic converter cooled down and needs to be warmed back up. 20 mins may not have been enough time to get the cat sufficiently warmed up, esp. after letting it cool down for 10 minutes. when you're at a complete stop, the ecu may think that it's okay to shut down the ice even though the cat is not warmed up since no emissions are being generated.
just a thought
