FYI I've had this same error once on an extremely cold morning and my truck only had around 10k miles on it at the time. I had other mornings equally as cold without any issues. Just wanted to throw that out there as parts of the country are experiencing cold weather.

yeah- i run it low prior to refill-
i think the time before the issue started it was so low it warned of limp mode in a certain number of miles due to being so low.
it is intermittent but has had me pull over to restart twice now due to miles and going into limp, so it is at the point of needing addressed.
need to figure my iphone and truck out with connecting to 4scan.
