Why does my car start initially and then fail to restart again after a trip?

What is your question?

Yesterday, I started it and turn it off, started it and turned it off, tryed to restart it again but it wouldn't. The gauges began to quiver and flutter and go up and down for a minute or so. After that, they went back to normal and the car started right up. The battery is a new NAPA Legend. The car never needs to be jumped in order to get it to start. The car also stalled at a traffic light the other day but started right back up when I turned it over. The car acts like this almost every use.
