Complete shut down. f

in slow traffic free 40 minutes the car shut down, flashers started. Had to push car with no power steering or brakes. Key would not eject and flashers not turn off. After 10 minutes starter fired up car and was lumpy for 5 minutes then ok. Worried it will happen again. Any clue on what I should have it tested for. 2012 Freelander2 HSE

Welcome buddy, bad luck! Post it up in the freelander section! With year and engine type. Sit back and wait!
Good luck!
