Similar Odd Power Outage problem too....
I have a similar odd power outage problem as well. Certain times of the day I have lost power to certain areas/rooms of my house but not the entire house. The power would be lost for a few seconds and then return. The longest has been like maybe 45 seconds but not over a minute. My bedroom loses all power (outlets and ceiling fans), second bedroom only the outlets lose power, home office only the outlet where my fax is connected to, living room wall outlet and ceiling fan outlet but not the outlet where my tv is hooked up and finally in the second bathroom all of the power is lost.
My dining room area is ok as well as my kitchen and main bathroom. ANY suggestions????
BTW an electrician came out and tightened some loose wires in the breaker box, which do not get tripped. I dont think he checked all of the outlets also.
