I have a 2003 2500 4x4 CTD with 78000 miles and the truck has been running great. Today i stopped at stop sign and the truck just died, I cranked it for a few secs and it restarted but then died again, waited about 30 seconds and cranked it over and it started and I continued home with no other issues , have gone out 2 more times and the truck starts right up and idles fine? Does this sound like the symptons of the fuel transfer pump starting to go or something else?
