im new .I just bought an 04 dodge 3500 dually and it has ran fine .Then the other day it died so i pulled codes and it had p0628 so i called dodge and they said it was lift pump in tank was bad . so i bought a new one and installed it . the truck still does the same thing it will start and run about 30 sec. and die like someone turned the key off but all lights and gauges are on and the check engine light comes on if you reset key it will do same thing over and over. you can give it throttle while its runing and it runs fine . Does anyone have any suggestions thanks

i installed new filter when i put the pump in and even tried a another one to see if i got abad one.when i pull the filter out the bowl is still full of fuel
