1800 PSI electric pressure washer. Occassionally after using it for 15-20 minutes if you release the trigger it won't start back up for a few minutes. I belive the issue is likely a gummed up pressure switch that is sticking. I ran it yesterday for over an hour with zero issues. I will include a partial bottle of pump protector that cleans and lubricates the pump and the pressure switch in the pump.
This is better for smaller jobs so I have chose to keep my gas pressure washer. $50
