crankshaft sensor or bad coil pack

A bad coil pack will just make it run very rough. A bad crank sensor or cam sensor on the other hand, will do as you described, as will a bad fuel pump. Luckily, all are reasonably easy fixes as even your fuel pump is accessible through your trunk. That said, The crank sensor involves pulling off the crank pulley, and the fuel pump in a GM veh is usually a little spendy, though a little cheaper on Amazon.
