Which process is eating up the CPU? Can u post a "show proc cpu |
exclude 0.00" as well as an "show ver" and "show align" when the problem
happens? 

It could be CSCds63384, not sure until I see "show ver" and "show
align"..

You might also want to upgrade to a more recent IOS release, I'd
recommend 12.2(2)XB11, but make sure you do some lab-tests before you
upgrade as the PPP and AAA code is much differnt in 12.2T/12.2XB
compared to previous versions...
