The problem I had most commonly in many hundreds of hours under diesel was
air getting into the line. the least bit of air getting into the fuel line
will accumulate till it shuts the engine down, replacing the fuel line might
be worth doing.

I'd change the filters, re-prime and retest.

Also it's possible that the injector pump or lift pump has a defective
check valve thats allowing the fuel to drain off and not allow it to be
pumped into the injector pump.

The problem I had with my diesel, at one time, was an hair line crack in the
high pressure metal tube fuel line. We tried every thing to repair it
including welding/brazing with silver. It would rung for several hours then
stop. The solution was to replace the metal fuel line with a new one.

Replace the high pressure line and inspect the fittings they go into.
Next, consider putting an electric fuel pump in series with your
mechanical low pressure pump. This makes priming the system much
easier.
