Code 12 The battery has been disconnected and the computer (ECU) has been reset.
Code 51 running too lean,
Code 55 End of fault code list
The 51 is what I feel is the problem. Here is a list of things to check:
Poor wiring condition at O2 sensor
Bad O2 sensor
Weak fuel pressure
Start with the checking fuel pressure. Do this when the problem occurs. Check O2 sensor while the engine is running (with a live scanner) to determine if it is working within the parameters. Check the wiring at the O2 sensor to confirm it is in good condition and not corroded.
Let me know what you find.
