This problem is either that the engine RPM is too low (most likely), or that there is something amiss in the voltage regulation. Get yourself a DMM that measures Hz, plug it into the output and see if you get 61.5 Hz, if not look for the adjustment on the governor spring. On some Powermates this is a screw that pressed on the governor arm, on others it's a little tab the governor spring attaches to that you bend. Do this at no load. FWIW 61.5 Hz is also 3750 RPM of the engine.

If this is one of the big "taco cart" portables you need to check that the vent on the gas cap is open when you're running the engine. In the center of the gage on the gas cap is a little knurled knob, turn it counter clockwise (lefty loosey), about a half turn or so and run the generator.
If that doesn't solve your problem add to it here, otherwise please give me a rating I'm trying to build a little credibility here and could use the help.

The problem is that the printed circuit board inside the generator draws a little current from the battery even when the generator is not running. Over the course of a few days this can make the battery weak enough to be unable to get recharged by the built in running charger which results in not enough power to run the electronic governor on the generator. Usually the spark plugs will work even with a fairly low battery.
Most of the Generac generators come with a built in trickle charger that runs off of the transfer switch load terminals. If your built in charger isn't doing the job it's either broken or you have the wrong sort of battery installed in the generator.

Your RPM's are too high. There is no voltage regulator in coleman generators (generator is actually made by generac) and is 100% dependent on engine speed. There is a screw under the tank when your looking in from the recoil side. It controls the governor arm. Screw it in and it incresses the rpm, out decrease. Plug something in that draws a decent load while setting the rpms since you want it to put out 120 and 240 underload. Your idle voltage does not matter.

the instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it
