5. Battery nearly discharged.
6. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.

I had an 07, I had to remove the lower and side fairings and then the bolts are visible, dont just lift it up because wires and the fuel line will be connected and tight. When you lift it, lift easily so you dont just rip everything, you should be able to lift it high enough to disconect the wires without damage.

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!!

Park the bike in a flat, easily accessible area, and stand the bike on its center stand. This will make the bike much easier to work on, and less likely to fall...drain coolant.
Use a standard Phillips screwdriver to remove the motorcycle's radiator shroud covers. On most Honda CBR models, the shroud covers will be secured by only three bolts...disconnect electrical end connections on the bottom edge of the radiator fan. Look for things like solder gapping, bubbling and corroding...Remove coolant hoses & mounting bolts & slide radiator and fan out. Inspect your hoses, flush and clean system. I would change thermostat now also. Make sure to use only Honda approved coolant when you refill. This is very important for the life of the pump and cooling system. Good luck, i hope this helps.
