[C320-list] air in fuel line?

[KEN GEIGER]

We had a similar sounding problem on  Vlovo engine in a Beneteau and it turned out the lift pump diaphragm was failing and leaking in air.

I've seen that with diesels before but it is usually little bit longer than a few seconds.  It is usually caused by a very dirty fuel filter or a greatly restricted fuel flow due to a blockage in the fuel line.  I wonder if it could also happened if the high pressure fuel pump is worn?
Hope it is something simple.
Best,

Hello,
My 1995 C-320 Perkins M-30 has developed a new quirk: it starts right up and dies suddenly after a few seconds. It will restart with a bit of cranking (c. 5 seconds). 
I’ve bled the system, tightened all hose clamps, looked for any diesel weeps. My thought is a small air leak, but can’t locate it. 
Any thoughts?
Thanks.
