I have an 06 Ram 2500 with a 5.9. Just came back from a 2500 mile trip and I got the code P0148 at least a half dozen times. Fortunately I have a Banks programmer that allows me to clear the code. After clearing it I could get it started (when the code came up the engine light came on and the truck would stall) and it would run ok for a while then do it again. After a few times I began to notice a pattern, it would occur every time the fuel gauge hit the half way mark. With a full tank of fuel, no problem but as soon as it got to half a tank it would throw the code. Sometimes it would stall immediately and sometimes it would go a few miles first. It acts like it's running out of fuel at half a tank. Since it runs great with a full tank I'm thinking it's the pump in the tank. Has anyone else experienced this?

 

draw straw might have come off the pump or cracked, so when the pump is no longer submerged it sucks air..

 

That's kind of what I was thinking but I've never had one out and wasn't sure what they looked like. Thanks for the reply.

 

yeah, only way to tell for sure is to either pull the bed or drop the tank...
