Default Possibly lean condition causing ls460 to stall

I'm not sure if the picture is being shown but I recently purchased a launch code scanner to check fuel trims and other data to see if the reason for my car stalling intermediately once turned on was having to do with my engine running too lean. So I guess I'm asking with the intake air temperature sensor throwing a code, is that basically telling me there's a bunch of unmetered air being sent to bank 1 that's not being compensated for to maintain a proper balance for the fuel trims? I know I need to check but my battery is currently charging just wanted a little insight to make sure I'm heading in the correct direction for my current diag. Any and all help would greatly be appreciated.

I also checked the voltage to the pins on the maf connectors and they were both at 5v for bank 1 & bank 2. I had 2 grounds 1 power and I'm assuming some sort of accessory power once the engine is started and the ecm is gathering the data being sent

You are stalling due to the cam/crank sensor issues.

I appreciate that sir, so just check to make sure I have solid power and grounds to ensure if it's the sensors themselves or a bad connection. Would all of the cam sensors run off the same power and ground wires?

Those inspection results are useless without error codes.

I believe those are the codes that were stored in the ecm

I would start with the crankshaft sensor. You will need to test it to determine its functionality.
