I need help!! Does anyone know why my 98 civic ex would be fine driving for a day then completely die on me the next? I just swapped a new y8 into it and the car was driving normally until the alternator died on me the other day, so I went and got a new alternator and battery and it drove fine until 10 minutes of me driving it barley tapping on my brakes it would shut everything off on the dash, then roughly another 10 minutes it just died on me again like it did the first time. If anyone knows this problem please help!!
