Small Engines (Lawn Mowers, etc.): B&S engine wont stay running, mud hut, gas model

Question
B&S 3.75hp motor starts but will not keep running.
This is a pressure washer I bought the end of 04.  The first year worked fine, but last year had to keep priming the motor till it ran for awhile..then it was ok.  This is the third time I will use it and now the motor will not keep going.  The unit has a fresh tank of gas.  
Model 10 D 902
Serial 0310 1752

Hi again Scott-
You say you found the main pickup clogged, was this the water inlet with the little screen?  I just got out my old lawn sprinkler tractor, it has an intake screen like my pressure washer- but believe it or not, a dirt wasp had somehow built a mud hut inside!  I had to disassemble the thing to get it working.  Beats me how it got in there- heh.

So... its runnin ok now?
