My car had white plugs with a new fuel filter and pump with no codes at all. Some cars just run lean by design to cut down on emissions.
Although, whatever is causing it to die may be causing it to run lean

You are guessing at a solution to solve the problem, rather than using the data the system is providing you. Code 67 = ECM detects transmission is not in neutral, reason why a KOER is not allowed to be ran.
Since your setup uses an automatic transmission, pin 30 of the ECM detects "in-neutral" state through the ground provided by the starter solenoid to frame contact, through the single post start voltage wire, through the transmission NSS switch, to the ECM connector. Do you have a separate push-button starter switch installed?... if not, you may have an open wire condition between the start wire at the solenoid and pin 30 at the ECM connector.
