5.3 no fuel

[Ken Davis]

My truck has 200 miles on new build yesterday I was driving and it quit and I had to trailer home. After it sits for about 15 minutes it wil start and run for about 1 minute the fuel pressure starts off at 50lbs then starts going down to 10lbs truck dies the pump runs for a few seconds then dies at the end the pump sounds different. The truck did this 100 miles ago I removed the tank which is a rock valley stainless tank I checked the pump it worked fine I put the tank back in and it worked.
