There are redundant systems on modern planes that can handle multiple failures. If they’re saying it’s fuel related my guess is dirty jet fuel. It would explain a stuck fuel valve. There’s lots of ground crew checks before flight, and one is checking the fuel tanks for contamination. Just a speculation.
These switches are evidently monitored by the aircraft’s systems, as the investigators seem to know for a fact when these switches were moved. This is not a “failure”, unless the switch moved by itself.
I’m not sure why you’re trying to “I reckon” this, when we know why the engines stopped.
