I have one that will shut off pressure when the water supply varies. Check your water tap, make sure all your connections are TIGHT. If not they will suck air and interrupt and pump cycle. Use new hose washers on everything. The engine (mine is Honda) will also buck in response to varying flow demand. It has an auto-close spring/lever to prevent it from overrunning if it loses incoming water. Good luck.

this can be that you need to bleed the system of air or that there is a problem with your trigger gun sticking when you release the trigger. These are two things I would check before you go into the machine.
