Generator alarm underspeed
When you get the under speed alarm is the generator under load? Try manually starting the generator with no load and let it run for a while, if no alarm, then put it under your home load and measure current draw (maybe have an electrician check it) if the amp draw and in rush caused by compressors, pumps motors etc are within the generator rating, check your fuel pressure, on average 8-11 WC Nat gas. Pressure may test well under no load but drop starving the engine of fuel unde rload. Underspeed is just that engine cannot make RPM/Frequency

Generac 5793 Ix 2000 surging
It sounds as though there is an issue with the carburetor. If the unit is "surging" with no load I would recommend thoroughly cleaning the carb. It would also be a good idea to test the fuel pump. Per Generac you need to disconnect the fuel line leading to the carb and pull the starter rope over to see if adequate fuel is flowing. If none of this is the issue try testing the stepper motor on top of the carb. If you unclip the wire and use an OHM meter all wires should test at 150 ohms. to test place on test lead on the blue wire and move the other lead to the remaining four wires. The should all ohm out to roughly 150ohms. if this is not the case you need to replace the stepper motor.... Before you do any of this you should check for fresh fuel, a good spark plug, and proper compression.

Check the charging voltage, while running should be 14.5VDC or higher but not more than 15.5VDC. If charging circuit is bad, you can use a trickle charger or repair the engines charging coils and regulator.
