Power washer - Pulsating under load

Video of issue

Generac Gas Power Washer

-Seems to be pressure related, not engine.
-Hose is in good shape, supply pressure is good.
-No issues when trigger is not engaged.
-It doesn’t drop pressure or have low pressure for an extended period of time, it just pulses between high pressure and low pressure, about one second each... only when the trigger is pulled.
-When nozzle tip is removed from wand, and trigger is depressed, it flows water freely without pulsing.

Please help!

That looks like a water supply issue, kinked hose, etc...

That's what I was thinking also. Maybe a piece of trash partially blocking the supply??
