I would suspect moisture in the trans electrical connector. After a restart, the car is warm enough to dry out the pins.

Disconnect that connector and spray inside it and the trans jack with electrical contact cleaner. Apply dielectric grease to the pins and around where the connector should seal when hooked up.

I bet that solves your problem.
