I have a pressure pro 5.6 gallon per minute sled mounted belt drive unit with a General TS2021 pump.  The other day I started it up and the engine runs fine until I pull the trigger and it bogs down and the  pressure and volume, obviously, drops off.  I removed the unloader, connected the hose directly to the pump and ziptied the wand and started the engine but with the same bogged down engine.  The oil in the pump looks good.  The air filter on the engine is good.  It has plugs and oil that are barely a month old.  Any ideas of where to start before tearing into the pump or engine?

Thanks for any help.
