My Kranzle Powerwasher is Acting up?

I work at an animal shelter and we use a power washer to clean the dog kennels in the mornings and evenings. We had perfect service by this stupid thing until about a year, or six months after we got it. It started to shut off on its own (the machine is now at least two years old).

We had perfect service by this stupid thing until about a year, or six months after we got it.
It started to shut off on its own (the machine is now at least two years old).
At the time and previously the shelter staff and I really didnt think about it much.

Then it started to get more and more frequent.
Ive searched the internet at home and at work, and the only things I can find about MY certain power washer, is that its a great machine for the money that is used to buy it.
Honestly, I could care less how much the machine costs as its screwing up every day now.
Its also becoming more frequent in the fact that instead of turning itself back on (it does have an idle feature, that shuts off the machine when its not in use for so many minutes or whatever), after it turns itself off, its now not even turning itself back on.
We have to physically go back there, shut it off, and turn it back on.

All of the seals are perfectly fine, nothing is rusted, the machine is clean (we clean it everyday because of the dog hair), it has plenty of water and soap supply, and the nozzle and hose isnt broken whatsoever.
I dont know what the hell is going on with this thing, but its now taking us two or three hours (depending on how fast you want to walk up and down the kennel "road" to go push the machines buttons) to clean our kennels.
And thats time better spent elsewhere.

Any tips, tricks, suggestions, links or someone pointing me in the right direction, would be greatly, GREATLY appreciated!!

NOTE:
Its a Kranzle Quadro 499 TST model.
Update: All seals, liquids, hookups, hoses and other machinery have been checked and been found okay and working properly. There is enough oil in the machine, enough water going through the hose into the machine via the hookup, and the hose that is connected to the sprayer is connected correctly as well.

Everything is as it should be.
My boss came by here a moment ago (he doesnt work weekends), and said he couldnt find any reason why the machine was turning itself off and not coming back on.

I figured the idle feature was screwing up, but if its not turning back on automatically, its something else.
Is two years old for a power washer?
