So today i went for a good 100 mile drive, and my car just shut down on me. I mean driving just fine and bam... dead. Before it died the battery light came on and the rpm gauge was twitching up and down. And when i go to start it up (while im still moving when it died) sometimes i can tell that im not getting full power from the engine. Before it would happen once and be just fine, now when it happens it every 2 blocks. So needless to say im not driving it unless it have to. Any ideas whats going on?
