I've been experiencing this problem rececently. First it was once a week, now it's once a day. The engine would just turn off without hesitation. If the car is in gear, it feels like the car lost power (the door locks automatically unlock and lock) and the car gugs a little bit and will feel like somebody just push start your car with a 5sp. Yes, mine is a 5sp 6th accord. Engine can turn off any time (coasting or in gear). Any help would be much appreciated. Thanks
