Sounds like the alternator is the culprit. I had a very similar problem about a month ago. With mine everything was dimming and some warning light started to come on. When you rev the engine back up everything comes back. I took off the alternator the next day and had it bench tested. Turns out that it still worked, but the bearing was shot causing it to be hard turning under any load. Another way to tell if it is the alternator is there will be lots of black dust where the bearing is. If the alternator went all the way, the battery will be ruined as well. I recommend that you get the alternator bench tested at autozone. They do it for free. You can have you battery tested too. You wouldn't want to ruin a new battery if the alternator was indeed dead.
