If there really are no fault codes, it could be a faulty crank sensor. When they stop working the ECU doesnt notice as it just assumes the engine has stopped.

Definitely sounds like crankshaft sensor. Common fault in the EXX chassis.

I've also seen similar faults with dodgy injectors but I'm sure this would be highlighted via diagnosis.
