Most likely cause is a bad battery combined with a bad alternator, or a loss of fuel and spark together. Might be as simple as a really dirty air cleaner. Or maybe something related to fuel pressure, like a fuel pump relay, or even the Electronic Throttle Control (ETC). These are symptoms of "dying in flight" and there are many possible causes. You need to have a mechanic diagnose this.
