I am assuming the engine that drives the generator is shutting down.
Some simpler things to try might be blowing a fan into the compartment where the generator resides, or turning off all the electrical devices drawing power from the system. These tests should indicate if the system is overheating or if the current draw is excessive. A check of the fuel filter might be appropriate as well.
If no success there, read on.
If you don't have a service manual, get one. If you do have one, try this.
Check those things required for the engine to operate. Air, fuel and ignition. I would put special emphasis on ignition because that is the easiest to interrupt. Now look for the safety devices that will shut the engine down if it gets too hot as a result of decreased cooling air, too heavy a load, or any other reason. Once you find the safety device that is shutting things down you must determine whether or not it is acting as it should. That is to say is it faulty and causing the problem or is it sensing a real problem, interpreting it correctly and shutting the system down.
Good luck. Unless you are lucky this sort of problem can take some time to diagnose.

Check, and/or replace the fuel filter. If this doesn't correct the problem, your carb could be fouled internally. If that is the case, it would need to be rebuilt. Although rare, the ignition coil could also be faulty. If you are handy with diagnosing, hook a spark tester to the high tension lead to the spark plug, start it up and watch the spark tester to see if you lose spark when it starts to shut down. If it does, replace the coil. If it doesn't, refer back to step 2 above. Also, be careful not to change the regulated speed of the engine. They are set at a regulated RPM.

Many units have a "low oil cut off" check this.
Also some units cut off if overheating takes place.
