Since most generators are seldom used, gas left in the carburetor gunks up and stops up the passages.
Take lots of pix of the assembly. Pull the carb, remove the bowl and spray carb cleaner in all the holes you see. Don't let it back spray into your eyes. Wear safety glasses. Some holes/orifices may need to have a soft wire passed thru them.
Next time you store your generator, drain the gas, run the generator til all the gas is out of the carb. If you can get to the bowl w/o removing the carb, pull the bowl and spray the bowl and underside of the carb w/carb cleaner and reassemble.

Replace the thermistor. The cost is around $44.00

Sounds to me like it could be a few things... pretty interesting that it runs and shuts down...sits for a little while then fires back up. Could be something as simple as a bad ground.. maybe it needs cleaned.. if the ground is making very little contact.. the bike would run bad, and because its direct current it has to flow. The metal in the motor frame etc will hold so much DC current.. but *** soon as it load up the bike would stop sparking. Let it sit for a while, DC trickles into the battery through the slight contact, bike fires back up. OR could be bad venting of your fuel tank, or a partial clog at the pet ****.. the first is pretty easy to check, open your fuel cap and start the bike..if it does the same thing then its not a vent problem. One thing that does happen on the Radian, is the reserve fuel screen inside the tank comes loose, and then everything inside the that has built up over the years either partially clogs the pet ****, or the hose, or both. Take the tank off, pull the pet **** off..if it still has two intact tubes with good screens..you probably don't have any junk in your line..but I would pull the line off and blow through it any way... it could be some type of blockage, when the bike sets the fuel seep through, but when it runs it eventually creates a vaccuum that stops the fuel flow. Those are my two first thoughts... good luck!!

First locate the oil pressure switch and see if you can bypass it,then see if it runs. If not check the fuel filter and fuel pump,make sure solonoid for fuel pump is kicking on.
SOURCE: The generator starts up runs for about 15 seconds and shuts down.
Check the oil pressure switch
