Question about Garden
When you release the trigger the unloader valve senses the buildup of pressure or the interruption of the flow and is supposed to go into bypass mode and the flow will loop through the unloader valve. The water will heat up very quickly and will then exit through the thermal relief valve if you run it this way very long. You should never leave a pressure washer running for more than a few minutes or damage can occur. It appears your unloaded is not functioning as it should and it is not unloading. This will cause the engine to stall on some units. Check the bypass hose to make sure it is not clogged or collapsing, More than likely you need to purchase a new unloader as they are usually not repairable. You may be able to purchase a repair kit and rebuild the unit which I have done myself but in my experience you are better off just buying a new unloader. I have rebuilt a couple but the rebuild does not seem to work well for very long. Just get a new unloader for your pump.
