Whenever storing the generator for any length of time after use, it should be allowed to run out the gas from the carburetor by first shuttinig off the fuel petcock, to avoid the gas in the float bowl from deteriorating and gumming up the small idle passages. With the mandated ethanol additives that are used, the gas breaks down much faster than pure gasoline, so it's more crucial to do this prestorage maintenance.
Luckily the Yamaha incorporates a fuel petcock to make this simple to do, unlike other generators that don't enable the fuel to be turned off independently of the engine.

My toro snowblower keeps stalling. It starts up fine, but won't run continuously.

If you haven't already, dump out gas and put fresh in it and try this, if it doesn't work you will have to clean the carb, take it apart and clean all jets ports etc and put back together and you should be Good to Blow Snow, pretty common problem with Small Engines that set half the season.

If you have not been putting gas treatment in your gas to treat the ethenol they have been putting into the gas its a good chance its the needle valve in the carborator. If you live in a state that does not add ethenol to the gas disregard this advise.

Remove & Check Float bowl on carburettor for any foreign matter. If there is any, it could have got into jets causing engine to run lean (only run with choke) and not be able to carry load in this state. A cleanout of the carby would not hurt and check the fuel tank for any sediment as well.

Three years with that few miles sounds like a good candidate for bad gas. I would start by taking the carb off and cleaning it really well with carb cleaner.
