so for about the past 4 or 5 days my car has been cutting out randomly which is more noticable when im carrying a constant speed. But then shortly after cutting out it loses all power and dies completely after a couple seconds.Have to turn the car off and click back and forth to accessories 1-3 times and will fire back up.i figured maybe the fuel pump was getting weak and had to be primed to restart but i have a fuel press gauge in my car and it never changes and im actually putting out more fuel on a stock fuel press reg. than im supposed to be. so guessing maybe a short somewhere??? any help would be greatly appreciated
