You know, if I didn't know any better, I'd say you have a fuel pump trying to die. I only say that as I've had cars act up like that before. I've also had them act like that right before the ECU went kaput. It being a daily driver makes trying to do diagnostic work a luttle harder, but then you mentioned you can re-produce it in the driveway should make it easier to find.
So when this happened to you, was it within the 15 - 45min time frame that it's supposed to happen after the engine reached normal operating temperature? Also, this happens (to me at least) only during the summer months despite Honda stating this happens only during the winter months.
Yep. If the car is off for a short time after it was running at normal operating temperature, the hot soak situation occurs. If I let it sit for about 40 minutes it will start right back up as if nothing happened. If I leave the hood up then I can usually get it to start up sooner. And also, yes, this happens to me only after they stop selling summer blend gasoline here in NY. Runs perfectly fine during the summer months without a single issue. Past two years haven't had one issue from May until the end of September.
