Generac starts, but cuts out quickly

Replaced spark plug, air filter, roll-over valve. Cleaned carb and carb bowl.  Put in fresh gas.  Any idea what to check next? 
Model number 0060242, 3100 PSI, 2.7 GPM.  Hubby thinks I've lost my mind trying to fix it myself, and I'm beginning to think the same. Starts up, but doesn't even run long enough to adjust the choke.

    Try this as it may be the pump that is the problem. Have someone or if you can safety tie the cleaning wand trigger open and see if the engine will run. If it does then the unloader valve assembly is stuck. If doesn't and cleaning the carburetor doesn't then you probably need a new carburetor since Generac/Briggs doesn't provide any parts for the carburetor.

    Thanks, at least the carburetor is easy and fairly inexpensive to replace. I had checked the unloader valve and it appeared to be fine, and I had figured it was a fuel problem somewhere.

    I had a similar problem with an old Generac pressure washer.  It turned out to be the oil pressure switch, apparently it went bad and was telling the ignition that there was no oil.  A quick test is to remove the leads and connect the wires.  If the machine runs it's the switch and they are easily available and cheap.  If it doesn't run it's not the switch.  Obviously before doing this you will ensure there is oil in the machine.
