2011 Journey Mainstreet, 3.6L. Four times in the last 2 months the engine has died while driving, just stops as if you shut it off. After stopping I put my foot on the brake and hit the start button, engine cranks over but will not fire. Go home and get my truck so I can tow it back, away from the car aprox. 20 min. Get in and hit the start button, car starts right up! Same thing all four times. No check engine lights, no codes on OBD II. I'm at a loss, any ideas are welcome.
