Cavitation is what happens to liquids when they're being pumped but not moving... so it "stirs" bubbles in the liquid...
Think of it as your tires spinning -- it looks great but you're going nowhere...LOL
I was thinking that if the fuel was not moving continuously - that you'd have TWO issues -- no movement leads to pump heating up - and if you toss in cavitation - caused by a pump that is "spinning it's wheels" - then you're also going to loose pressure - since we know bubbles don't move like liquid (ala air in a brake line)
