Cisco Asa 5505 ppoe connectivity issue

[billybluelight]

Hi to all, I have configured my asa with a pppoe connection over an adsl modem, the connection works fine until the power goes off to the asa and the connection will not re-establish. The only cure I have found is to reset and reprogram and then the connection is then re-established until the power goes off again. Any help would be much appreciated. I'm guessing that I have missed a command or two but cannot find any more reference in my ASA guide. Here is a copy of the running conf,
