Car shuts off when shifting automatic transmission from park to reverse.

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Typically when I've seen this in the past it's due to an internal transmission conflict causing the transmission to stall the engine. This is likely due to internal mechanical concerns. I would recommend the transmission be evaluated by an expert at a local shop near you. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
