OK, my 5.5 gpm hot water skid (honda 20hp, general TS2021 pump) took a dump on me today. I've been working her for the last 3 1/2 weeks at 10-12 hrs per day (at least 8 hrs steady run time). We've been using turbo nozzles and removing paint - yes I'm hurting. This skid is 3 yrs old, and has a fairly new unloader, newer coil, newer flow switch, etc. I am pretty handy, and a licensed engineer to boot, so I've covered the obvious stuff. So while spraying, the pressure will dip real low and back to normal several times, then ultimately the motor dies. Its only doing it under load, and after it warms up. Belts are fine, and there's no water restrictions or flow problems. I've narrowed this down to either a blockage in the fuel system, or maybe my pump is going. I've never had a pump go on me, but since I'm really taxing this unit lately, I think it might be going. I'm going to pull the tank and clean the entire fuel system from tank to carb tomorrow, but if you know its something else, please chime in.
