Answer: Jackie,
Sounds like you could have an issue with your car's transmission computer getting too warm. When eletronics get overheated, they can act erratically. While you're driving, there is most likely some sort of cooling effect on the computer. But come to stop, and all that heat starts to soak in the eletronics, causing them malfunction until they cool down.

I would recommend you have a transmission shop inspect your transmission and have the fluid flushed if you've never had that done before. Also have them inspect the transmission computer for possible damage.
Good luck!
