Well the first thing I would suspect is the engine overheated. I would check the engine oil and coolant to make sure there is sufficient amount of each. I would then check the engine codes for a fault that can tell you where to start looking for engine failure. I would recommend a technician from YourMechanic come out and inspect your car to see if they can better assess the situation.
