Ford Focus battery light comes on when stopped and car wants to stall?

I was driving my 2002 Ford Focus ZX5 with the DOHC engine. I went to the grocery store and as i sat in my idling car, the battery light comes on and then approximately 1 minute after the car was put in park, the battery light comes on and the car stalls out. This then happened the 2 following times i put my car in park. But then after that, the car seemed to run/stop fine. It happened one time afterwards as well when i was at a light, but the car was not in park. When the car's stalling, you can hit the gas and will keep the car alive. The battery, coil pack, plugs, and wires were replaced 2 days ago. What could it mean? Fuel filter replacing? Any help would be appreciated!

Put the crystal into the Focus Ring (center of the machine)
2. Talk to Paratus "What do I now?"
3. Postion yourself in front of that Focus Ring (there's little platform you can go/climb up, so you stand right before the focus ring)
4. Use "frostbite" short(ly) and watch the beams behave, if the lightbeams take postions from where they can be reached of each of the three lenses head for the adjustment of the lenses. The positions Britney posted work 100%!

If step 4 is not working out for you, try "flames" on the crystal short(ly) to Reset the position of the beams TEST: With engine ON but the car in PARK, put on the brakes. IF the idle gets rough and/or slows, have the vacuum booster on the power brakes checked for a vacuum leak. If that's OK, turn-on the A/C and see if it idles better in traffic. My girlfriend's 2003 ZX3 with that same engine also idles rough, and turning on the A/C helps. Get your battery and alternator tested. One or both could be going bad. Common problem with Fords. You need to clean the throttle body and the air by pass solenoid. Google it for instructions there are a few video on how to do it. Check the alternator Check the charging system fuse before you start buying things. The battery light comes on because the alternator output drops below a certain engine RPM. This happens during an engine stall. It is not a symptom of what's wrong with your car. The problem you describe is a common issue with the Ford Focus, regardless of sub-model. It is difficult to diagnose here so you should take it to someone knowledgeable for an in person diagnoses.
