Age is one factor, electronics such as printed circuit boards deteriorate with age. Another factor is malfunction of the cut-out or electric regulator. Too much and too high current from the regulator will burn the CDI out in seconds if a fuse does not go first.
Age. Damaged. dirty
Normally, they don't start to go bad. They either die outright or have moments where they'll just work or not but doesn't last long that way. But be sure to test the output of the pulse coil and the kill switch before condemning the CDI box.
Sorry you can't rebuild a CDI box, as a matter of fact you really can't even diagnose it as bad (usually, a few rare bikes have the ability to be tested), you just have to rule out everything else first. Considering Just how much a CDI box costs you DEFINITELY want to confirm that everything else is ok first. The only other way to check the CDI is if you have a friend with THE EXACT SAME BIKE! Try and talk them in to swaping with you, just to see if it'll run. However if there is something on your bike causing the CDI to go bad, be prepared to buy both of you a new CDI. Good Luck.

bad roads, potholes, and being hard on your brakes. Eventually, they will "go bad" due to normal wear and tear.
Yes, but they are easy to replace.
The good ones go in the fuse box and the bad ones go in the trash.
