Lean mixture.
Yep, that's the first thing to check. If you are running the genny at close to sea level while adjusted for high altitude operation (lean) that would do it. If your main jet is plugged, or, you have a vacuum leak in the intake, that would do it too, but check the altitude adjustment first since it's easy.
