   Mine does the same, just started doing it yesterday.  And mine doesn't die, it just shuts down (when it dies the light on the console stays on for a second as it is stopping, but my light goes out and the genset turns off).  Sometimes I can lightly load it (microwave clock, fan) but as soon as I turn on the AC down she goes.  Any help would be GREAT!

   Almost all genset have their own specification (minimum load running). In my factory, we have big engine and if the load only < 40% from its rating, the engine will be stop (shut off) -- electrically interlock.
   
   Some sources say, 30% from its power rating is the minimum load should be considered for every genset. In some application, load bank is installed also to cover underload condition.
   Running the genset under 30% of its prime rating will resulting engine damage.
