Wont start up after shutting itself down while driving

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. When the vehicle shuts down, does the engine crank without starting? Or are there no lights or electrical power? Or are there lights and no engine cranking? The description you share and the inability to test the vehicle hands on leaves me with a bit of a loss of direction or suggestion. I'd love to give you some guidance, but if all we have is drove and shut down -- it really requires hands on testing from a shop near you. I'd suggest making a good relationship with a shop near you that can help -- https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
