You can see that the router is crashed with "Bus Error exception". so when it comes up on its own, you can issue "show stack" and plug the output in following output intepreter by slecting "shpw stack"

https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl

and see the results.

If the router keep crashing like that, its a hardware issue. so try to change the Network Module with the WIC-1ADSL card or try the same card in the other 2621XM if you have. But at this point it looks a harware issue.
