Okay. UPDATE.

Verrrrrrrrrrry strange. I went downstairs with my roommate, we had some errands to do, and I was going to try to turn it over one last time. As I was walking towards my car I remembered I had my remote starter and wanted to see how that would work out.

WELL. It turned my car over and it's been running smoothly since. I also turned it off and then back on with the key, so it can't be the key ignition could it?

I don't want this too happen again. I was very scared. ANY clue what it could be? =[
