You'll want to to talk to the in house 12V guru "ISX" he'll have a good idea why this problem is happening.

Sounds like it is getting air in the system. I would check all the fuel lines for line deterioation or damage or loose clamps or fittings. The 12valves are notorious for having the fuel lines get rotten. Wish I had a dollar in my pocket for every inch of fuel hose I have replaced on them.
