once you prime the filter it will run fine ?
if you run a fuel line form the pump to a 5 gallon gas can of diesel fuel will it still die out ?
form the lift pump
bypass everything to the pump with a rubber fuel line into a 5 gallon of fuel
if it still does this the odds are there is an internal failure going on inside of the pump for the optic cam sensor which is not serviced and is part of the pump
if it will not do this with that set up then there is an issue with that fuel feed line or return from the pump to the tank
