GE freezer on bottom.Shuts off, acts like computer reseting

The control panel seems to loose power and then reboots, no lights inside or out when it happens. Like all power has been lost. once in a while i tap the left door where the digital display is and it seems to boot back on.
Do I need a control panel, or control computer :confused:
How can I check this for problems?

To enter self diagnostics during normal operation of the refrigerator press the ENERGY SAVER and ALARM/LIGHT pads for six seconds. The display will beep and flash. Continue to press both pads for an additional two seconds to enter the self-diagnostic mode. If any failure functions are present, those segments will now begin to flash.
