Thanks for all you help.
This is probably what caused your problem. The plug wire screws into the CDI unit. If it is loose I cut a bit off with some wire cutters and I apply some silicone cement on the sides before screwing it back in. Make sure you don't get the silicone on the end where it makes contact.
It is pretty easy to dislodge this while working on the bike. I usually replace my wire with a longer automotive one and place the CDI box under the motor where it is out of the way.
