Has anything been replaced recently such as the engine? Did it start doing this after a repair? Is the radio aftermarket?
It almost sounds like a ground was left loose somewhere or you have a loose connection. Check the connector for the fan and the ground if possible look for corrosion or loose connection.

Check your battery connections, make sure they are not corroded or loose and have the battery tested. If you have a weak battery it could be that with the fan coming on, the voltage is dropping so low that modules are shutting down. If the battery is OK then test the charging system.

If you have a wiring diagram post it on here please.

Yup like Aaron said I would check the battery connections first make sure there tight,clean and making good contact. If your still having the problem do a voltage check on the alternator then take it from there. If the voltage is dropping low enough where all electrical turns off it's stalling because the fuel pump is not getting power also
