I have a router that appears to be rebooting ever 20min to 1 hour. I don't have much experience in troubleshooting this type of thing so, I'm hoping I get a little help here. I've pasted some information from various show commands below. If anyone has an idea I'd appreciate it.

Sounds like your power supply may be flaking out. Is the system connected to an ups?
