I have a 2000 Hyundai Accent 1.5 SOHC that won't start. I'm not really sure if this is in other threads but I can't seem to find anything. So i'll just explain what happened.

I started the a car and started fine took two turns then it just shut off and would not start again. I got the battery changed and it started fine then about an hour later while i was driving the car it shut off then speed decreased and did not start again. Also while I was driving, whenever i hit some bumpy roads my radio and everything would shut off for a second then turn back on. The lights inside the car as well as the headlights and high beams are working fine.

Hope someone has any ideas of what maybe wrong.
