Same think happened to me when I retrofitted with a rotary pump.
It is caused by air in the feed water. Prime the pump and make sure
that there is no air leak in the hose feeding the pump.

I have this same problem, though I have not measured a drop in
pressure (either on the pressurestat or with an external brew pressure
gauge). It does mainly happens if the pump has to work hard, like on
a tight slow pour, and it might sqwark (a pretty good word for the
sound, BTW!) once total or once every couple seconds for part of the
pour. I'm not mechanical, but the frequency and sound make it seem
like a sqwark per revolution of the internal mechanism on a rotary pump.
The problem started happened infrequently maybe a year ago and has
gotten more frequent since. But part of the trouble in my case is
that I just replaced the pump maybe 2 years ago with parts and
instructions from WLL. I'm wondering: is it possible that I
installed something incorrectly that led to this so soon after
replacing? Or does that sound like a bad part? And either way, what
to do now?
