Dewalt pressure washer idles too low when warm

Anyone know what would cause this? The pressure washer works great when started, but after a minute or two, the engine drops in Idle and the pressure goes down. I havn't been able to find any throttle adjustment screws on the carb. Any one know what might be happening? Thank you!

Post your model number so the experts can look it up.

Also, you mention that the idle speed drops but you also mention that the pressure goes down. People usually talk about the pressure when it's reved up. Is your high speed dropping or is it really the idle speed that's dropping?

Now that you mention that, it seems to idle down and then not idle up when I pull the trigger. Any instant go to when that happens? Ill get the model number tomorrow.

That's a problem with the unloader valve.
