check the belt. bad belt/tensioning means no alternator rotation (turns off) and no ac compressor rotation (no cold air). squealing when turned on indicates bad belt/tensioning.
I don't know how to explain it turning on again after you pull the battery cable.

On newer vehicles the radio is tied into the BUS system. With this system a faulty component on the BUS line can pull the whole system down. Unplug the radio connectors and try it for a few days and see if this is your problem.
