Engine shuts down when slowing down, turning into drive way, nothing consistent but seems to happen only when slowing down but intermittent. CXL Model

Have someone try cleaning the electronic throttle body.

The electronic throttle body is what controls the engines idle speed whenever the accelerator is released.
