I have a two year old DP3100 that suddenly quits running under load.  It worked fine last week when I cleaned a 20' x 40' pool cover.  I have it connected to a city water supply with a 5/8" hose at at least 40 psi.  It will run fine for a few minutes or less and then the engine shuts down.  It starts normally, but quits running after it warms up.  Any ideas?  Thanks.

I believe that model has a low oil level sensor that will shut down the motor. Try checking your oil level. If that does not work, you may have a fuel supply issue.

Good Catch!  Thanks JC!

The operative word here is RTFM (Read The Freaking Manual).  I gagged this problem on two fronts.

1.  I had forgotten about the "Oil Alert" feature of the engine as detailed in the Honda manual that came with the unit.

2.  I also was checking the oil level incorrectly.  I was reading the dipstick with the plug screwed all the way in.  The manual clearly states to check the oil level by butting the plug up to the opening.  I always check the oil level in all of my gas powered tools prior to using them, but I was always getting a reading that was falsely too high on this one.   

I filled the crankcase to the proper level and the unit runs as it should.
