How about another uninformed opinion?

Check vacuum lines and inspect for any breaches in and around the intakes.

If the combustion chamber is sucking more air than what would normally be "metered", that would cause a lean condition, especially under "load".

I would presume that the engine management system would compensate for that, but it would be something I would inspect.

BTW, how long has this been occurring? Any recent repairs done in the engine bay prior to the incident?
