Its the vent tube not letting air out for whatever reason.
Mine does this every once and a blue moon and when it does I pour a bottle of injector cleaner or Seafoam down the vent tube using a small funnel.
Then the problem goes away.
I have no idea why it happens, I have gotten into the habit of pouring a bottle of injector cleaner into the vent tube once a year and I have not had any problems since I started this practice.

That explains it. I'll carry a can of Seafoam when a blue moon is approaching and - Bam! No worries.

+2 on the vent tube gettin clogged. If the air cant escape fast enough, the pump reads the pressure increase and decides its full and cuts off. Happens all the time with fleet vehicles, especially crown vics.
