  1. First thing to do is have the codes pulled.

    A guess would be the engine temp sensor. if it was stuck thinking it was still cold when it got warmed up, the engines computer would dump too much gas in , start sputtering and kill the engine.

  2. It could be a crank sensor and or the coil plate is bad. I had a pontiac that did the same thing and it was the coil plate and or the coil pack.
