Here is the definition for code 431.

P0431 MITSUBISHI Description The Engine Control Module (ECM) monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 (rear O2 sensor).

A three way catalyst converter (Manifold) with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase.

When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed. The problem could be the catalytic converter, one of the O2 sensors, or an air leak in the exhaust system.

Why wouldn't you have had the current drain diagnosed
to find out the problem?

Was the Alternator tested & found to be bad or either
battery found to be bad

We can't guess from the internet

The vehicle should have been properly
diagnosed & resolved long ago.

There are 300 or more people on this site a day,
who apparently don't know how to find any repair
shops or dealers that can resolve anything at all

The clock and radio memory use a different power source than the radio - - that source is not controlled by the key switch. I would check the fuses first to see if you blew one that is hot all the time.
