I agree, check the charging port. Perhaps there has been a little too much force while the charge connector was plugged in, and something has come loose inside, and sometimes short?
If you are brave enough you could take the xoom apart and see if the charging port is loose, and perhaps resolder it. Or remove the charging port if it is broken and start charging using a dock stand, if you have access to one.
