Are you in very cold area? If yes....do you use anti gel in your diesel? Not sure where you live but mine threw same code when the fuel gelled up on me in
-10F weather here in Missouri. Truck started and idled fine that morning....but drove down road about 6 miles and it cut out on me twice and threw p2291 code with "wrench" light on dash. I was able to limp off road onto parking lot and after 30 mins....truck started up and run ok. I got home and changed fuel filters and have had no issues since. I did have antigel (diesel kleen white btl) but it apparently didn't stop the gelling/waxing issue. Now I use Howes and have been consistently at or below freezing temps and single digits and negative temps for last 3 weeks without issues. Changes your filters....and pay close attention the the one in the separator....mine looked normal but once I removed the fine mesh outter covering...I saw some gel.
