2004.5 Cummins HO. Truck will start and run perfect...and then stall after a minute or two. No smoke or anything, just shuts off. The fuel filter and in-tank fuel pump have already been replaced (with no luck). Now for the weird part. I have a vegetable oil system on this truck. Separate heated tank, same injector pump and of course same injectors.....it runs PERFECT on vegetable oil! So, what is it between the diesel fuel tank and the injector pump that would cause the truck to stall and spit out a P0148 code? I guess the moral of the story is to run your truck on sushi juice
