if you do then you may have loose connections at an upstream outlet that feeds the dead ones due to bad connections for what ever reason. chase the feeds for those outlets back to the previous outlet in the same room or general area. take the cover plate off and use voltmeter to check upper and lower wire pairs while keeping a radio turned on plugged into the known dead outlets in case while you are probing you happen to activate one of the dead outlets downstream. good luck. with a little fault isolation you should figure this one out.
