Mine cut out for no good reason a week back. I normally get around 100-110miles before i need to switch to reserve. On this occasion I´d done 60miles so thought it very odd that it needed to switch to reserve to get it to start up again. When i refuelled later i only got just about a gallon and a half in so the average of 45mpg seems consistent. It´s been fine since. A month or so back it stuttered for about 200feet before returning to normal.
