    Keep an eye on the tach. If it drops to zero while its still running/right before it dies then I would say crankshaft position sensor. And no, they do not usually throw a CEL.

    Other than that could be a failing ignition control module (the metal plate that your coil packs mount onto).

    went through similar with my '08 except it would die randomly when coasting to a stop or at a stop. little more to the story ( where i ended up with crank but no start) but replaced a cracked coil and ICM and problem disappeared.
