If this is one of the big "taco cart" portables you need to check that the vent on the gas cap is open when you're running the engine. In the center of the gage on the gas cap is a little knurled knob, turn it counter clockwise (lefty loosey), about a half turn or so and run the generator.
If that doesn't solve your problem add to it here, otherwise please give me a rating I'm trying to build a little credibility here and could use the help.

    Does the generator have an automatic test run in place? I have some neighbors with a generator and it kicks on an off like that once a week. However, there was another individual who got the same type of generator and it was a lemon. I guess that happens on occasion as well. I don't think they had generac generators though.

    My Guardian 16KW


    I have never heard that generators need to be perfectly level to prevent generator damage. It doesn't compute -- auto generators/alternators run at all sorts of angles -- so do motors. And for the damage to occur in 2 hours running doesn't sound right either.

    It does sound like the generator itself is not working/generating properly, but I doubt it was caused by the slab.
