Well, at this point I'm inclined to agree with everyone who suspects the fuel. I filled up with my usual BP and took off for Gadsden last week (a little under three hours), which I drove non-stop and included some dead-stop traffic on the interstate. I drove back later in the day and was stuck in heavy stop and go traffic for at least an hour during the heat of the day. I experienced no issues during the trip. I suppose it's reasonable to assume I was using summer gas for this trip.
