Default Car won't start

So today, my battery died when I was at school. I went to class, and 2 hours later, when I came out, it wouldn't start. My friend gave me a boost, and everything seemed fine. I drove home, 2 or 3km, let it idle for a little while, and shut it off. I tried starting it again, took a little while, but that was expected..I didn't think the battery would be fully charged in that amount of time. Anyways, after letting it idle for about 20 minutes, I shut it off and started it up a couple times to make sure everything was working fine, and it was. After the 4th or 5th time, when I turned the ignition to "on," I lost all power. No interior lights, no dash lights, nothing. This kept going for a little while, then the BCM started clicking and chattering. I wiggled some wires on it, and I got my lights back, and the car started, then stalled. This kept happening until I pressed the gas once it started, and it stayed running. Until I shut it off again. I checked the battery while it was idling, and it was showing around 14V, and with the car off, about 12.6V.

Any ideas what my problem could be? I'm going out to try and clean my battery terminals when I warm up a little and get some feeling back to my hands.

EDIT: I forgot to mention, sometimes, when I try to start the car and the power doesn't go, the starter solenoid will click, and the fuel pump will prime fine..

I would start by getting the battery tested. Doesn't cost anything, and eliminates the obvious.

It was the battery cable after. I just got back from cleaning them. The positive had some corrosion and was a little loose

They battery seems fine, it'* only 2 years old, but I'm gonna keep an eye on it, just in case.

There should be one or two grounds coming off the black cable for your battery. Check those and clean/replace as needed.

Also if you have the AUX post check that and replace/clean as needed. It has a red cap on it that says AUX.

I checked the AUX post when i cleaned the others and it was just like new. It seems like it was just the corrosion on the pos terminal. Its running like it should again

Yeah, I'm definitely going to keep a close eye on everything, especially for the next couple days to make sure its working properly. It wasn't real loose, I guess just loose enough, along with the corrosion, to cause problems.

LOL On the Volvo I traded in for my Buick, I couldn't tighten the battery cables since I had to clear the codes every time I tried to start the car. Many weird things happen when driving with a battery terminal that isn't properly affixed.

(BTW, if you have a Volvo that is throwing all manner of bizarre codes, blowing black smoke out the tailpipe and misfiring, taking the cables off the battery and grounding the two battery cables to each other will reset the computer so you can drive again...)
