Unhappy Lean running Roadmaster

I am a new member, hope I can get some help. I have a 1996 Roadmaster sedan with the 5.7 LT1 motor. The computer code shows lean in left and right bank. This problem showed up rather suddenly. It ran fine, then I had difficulty starting it after it was not run for several days.

Once I get it running, it is obviously lean if I try to accelerate for a few minutes, then it seems to run OK.

If it were the fuel filter or fuel pump, it seems it would not get better after a few minutes of running.

I would appreciate any ideas. Thanks, jtg
