Mark, For a unit to shut of and come back on about 30 minutes later would be the unit going through the defrost cycle. With the refrigerator section not cooling properly you will want to make sure that the evaporator coils behind the freezer wall are not impacted with ice which would be caused by a defrost failure. At this point you will want to check continuity of the defrost heater and defrost bimetal. If either do not have continuity then the part that has no continuity would need to be replaced. If both check ok and it coils are impacted with ice then replace the defrost control.

Hello J.L., Two things I would go directly to if I were able to troubleshoot are the thermostat WP2204605 and the defrost timer W10822278. You should use the wiring diagram on the unit to follow the wiring out to the issue. If power is good to the the components mentioned, you should at that time start looking to a lost neutral connection. You should also check the outlet you are connecting it to. There is no reset button but there could be a connector unplugged.
