I have been having the same problem as many other Generac owners. The engine will start and run for a few minutes (it's gone from 15 minutes now down to about 3 seconds).
The fuel filters (inside the engine and in-line) were replaced.
The gas in the tank was thrown out and new gass added.
The carb was removed and all passages blown clean. The oil pressure cut-off was replaced with another one.
I have no specific info for your generator but the following should apply as it is a small engine-
When it dies, pull the spark plug and see if it is wet. If not wet, it is not getting gas- does it have a fuel pump? Try a gravity feed (hook a tank up to it and put the tank higher than the carb on the generator- if it runs it is a fuel issue.
If when you pull the plug it is wet, try to check for spark but-
drying the plug-
ground one end of the plug (as it is out of the cylinder head, on the top of the cylinder head and turn it over and have someone look to see if there is a spark in the gap as it is turned over.
A small engine needs a few things to run, gas, a spark and spark at the right time, and valves opening/closing at the right time.
If it is the timing, this could be a bigger deal...
Post how the tests go also- is the gas fresh? was old gas left in it?
Check the rubber fuel lines---gasohol rots the hose---it collapses---I have a Bounder I had a recall about gas and rubber lines---i replace mine---works fine now

If this generator is in a motorhome, try this; check your fuel guage. Between half and a quarter tank, the generator will not be supplied with fuel. The reason for this is if you are out camping in a remote area, you can use all the fuel, thus, your generator dies and you can't even start the motorhome to get out of there. I recently ran across this very same problem and it turned out he was just low on gas!
