DTC 55 Fuel Lean Monitor

I pulled this code from the PCM last night.
DTC 55 Fuel Lean Monitor

I have about 3000miles on my lt1 ('95) swap into a '84. The car has been running like a champ, untill last week above 3000 rpm it falls on its face.

I don't have a clue as to what this code means. Should I start with the fuel pressure?
