871 Goofiness

I configured a site-to-site VPN using the (noob) SDM wizard on two 871s between a site in MN and one in WI. The one in WI went down today, and we had to drive out there to check it out. There was no link light for the 871's WAN or on the DSL modem, and I couldn't ping the 871's internal interface. I was really well prepared, so I didn't have a console cable on me.

Out of options, I power-cycled the router, and I was able to ping it, access it via SDM, and it started handing out IPs via DHCP again. Oddly, the site-to-site VPN was gone. I thought that was weird, but it was easy enough to recreate, so I didn't worry too much about it. We no sooner arrived back in MN when we got a call saying that it was down again and power-cycling it didn't help (I made sure to save the config before leaving). Is this just a fluke hardware problem, or is there something else that would cause this? It's ran flawlessly since October or so.

Tell us what you see.... Best if you issue these commands as soon as it goes down...

We had a 7206VXR intermittently reboot all of a sudden recently due to a fault on the board...... It had been running flawlessly for 4 years....

So the guy that's having the problems just replied with this a little while ago, "OK. It seems that if I unplug the Cisco box for a while I can get about 1 hour of use which is enough time..."

Is that odd or what?

Overheating/power supply issue

Hardware fault that is making it crash. Probably what miller811 said and it is a power or overheating issue. I've had a router act weirdly and crash every few days because of bad RAM as well.
