well my dad didnt get a chance to go into the dealer because it is his work truck and he keeps getting called out. Now it is throwing a po148 and thats it and he says if you let the fuel get down to less than half a tank he can just be going down the road and it will die on him. any suggestions would be greatly appreciated oh by the way its an 07 5.9 6 speed

 

in tank lift pump(fuel tranfer) is dying
0148 code is the l/p code. heres the code list for future reference.
