Leaving slowly shuts off motor. Start rehabs it starts restart leaving at slow moving it stops. If you start on pedal down, it goes great. I went through a 15 mile slow driving it would shut down every time to move to forward it could drive to California. Just do not go really slow to move forward slowly. Jim

It does sound like the car is in limp mode which is common when the throttle body actuator needs to be serviced. also, we need to run the codes to see what comes up. here are two guides to help us fix the problem and do the scan which is easy:

The dirt in the throttles bore makes it loose correlation between the throttle pedals sensor and the throttle body which shuts the operation down.

Let us know what happens and please upload pictures or videos of the problem.
