Yes, It is due to a power issue, but if you are sure that there is no problem with the power during the power recycling of the router, you will have to check the following,

1) Check the router cabling, Power socket.

2) Check whether the device is getting proper earthing if it is racked up with a group of devices.

3) check "sh envi" just to see whether  the devices are working fine.

If you are still facing the problem and you are sure that there is no power problem at your premises during that time, go ahead and take sh tech support and have cisco TAC investigated on this...:) Hope this helps..
