Try zeroizing then recreating the crypto key and see what happens . Possibly the key got corrupted or blown away with the power outage.

Thank you ,
do you think following command would be enough?
crypto key zeroize rsa
(make changes)
crypto key generate rsa
(verify ssh then remove telnet) ?

Yes , that would be the first thing I try .
