Intermittent no start, no CEL codes

My 2000 Aero was running fine until the other morning when I tried to start it and all I got was a very weak crank, hardly any at all. I charged the battery, and car started up fine. The battery was 4+ years old, so I bought a new one, installed it, and car started right up. Next morning, hardly any crank at all. Last night I charged the battery again and got good cranking, but the car wouldn’t start. With the key in the on position, I could hear the 2 second fuel pump hum, so the fuel pump seems to be working, plus it doesn’t feel like a fuel problem.
This morning I tried it again expecting to get very weak crank, but there was a good crank and after a few seconds the engine started to sputter to life, then after another second or two, it fired up and ran fine. No check engine lights, and the SID check showed everything as OK. I let it run for a few minutes, then turned it off and tried it again, and it started right up. Turned it off and tried again, and it started right up. Any thoughts?
