Sprayer quits after only about ten seconds

This pressure washer is well made and laid out well and comes with a 25 foot hose which are all pluses. The bad is it keeps shutting down every 8 to 10 seconds which requires releasing the spray trigger to get it to re-prime. Ive read you must run water thru the unit and get a good flow going which I did and still no luck. I'm shipping this one back and will see what happens with a new one. UPDATE: Still the problem continues with the new pressure washer. It may go about 20 seconds now but I am experiencing the same issue. Ive had a couple of electric washers before this purchase and this one has the best features over the others and so I was hoping that it would work better. I noticed that the water flow is weak when priming and so maybe these water flow restrictors, to keep at 1.4 GPM, are keeping the water flow down and should be a little larger. I upgraded a star since it is working a little better but still not really right. I have a few weeks to decide what I will do with this unit.
