In the 1,500's for awhile, but sometimes after it runs awhile it will drop in the 900's and act like it's trying to shut off.

Can you back off the base idle screw until the idle drops down? It sounds like the throttle plat is open too much which is raising the voltage and when the voltage is high, the ECM is changing the fuel mapping.

What happens when it is disconnected? The idle should drop to 500-600 RPM.

Long term trim bank 1 and bank 2. It could be in percentage or it could be in voltage.
It will tell me if the engine is rich or lean.

Nuts. It does not give the trims and the mass air flow sensor readings.
The O2 sensor readings are full lean.
That tells me there is a lack of fuel.

I know you replaced all that. We have been over that many times. No to the fuses. If it was, you would not have any voltage to the sensors and a ton of codes.
With the engine running, remove the PCV valve and then remove the oil fill cap. Can you feel vacuum or pressure?
This is with the engine running.
