Symptom seems to indicate a fault with the radio unit itself. Party of a circuit is intermittently not working and quite often it is due to a bad capacitor within the circuit.
A loose wire connector could also be the cause and you can try starting with removing the radio unit to check the connectors
If you have any friends that does electronic component repairs, you can consider seeking their help.
