I am going to say that its your battery dude. If it were your alternator your car would start then die a little ways down the road. But since you say you charge it then run your car then after you shut it off it won't turn over that makes me lean towards the battery.

turn on the car.
once is running, disconect the battery, if it stays running the problem is your battery, if it dies you need a new alternator. I assume is your battery, by what you describe, but the test won't take you more than 5 minutes. --------------------  |

You may have bad cell in your battery or bad connection on the posts. Also check any possible draw from the battery. |
