Take a look beneath the fuel injection pump distributor head. Is it wet? If fuel is leaking from the pump head seal it may also be sucking air into the pump. Here's your fix: Dieselgeek has a $10 fix complete with instructions.
While you're at it, check the case pressure relief valve. This thread is pertinent: http://forums.tdiclub.com/showthread.php?t=194607
Hope that helps.

Question - what could be causing this failure? It's periodic, but incredibly annoying. I hope it's not a fuel pump problem.
