Another pressure washer

This one is made by Delta Shopmaster, 2450PSI with a Honda engine 5.5hp. (DTH2450-1)

The engine and the pump run great for short periods. Then all of a sudden, while I'm spraying, the engine gets bogged down. If I release the trigger on the sprayer, it'll pick back up to normal. If I don't release the trigger, it'll bogged down for a couple of seconds and either pick back up on it's own, or it'll die.

I'm guessing it's building up too much pressure in the pump. If so, what can I do, or where should I start looking?

There is a pressure release valve on most pumps. Some are adjustable. Yours may need to be adjusted or cleaned.Look at your manual.
