I need help... When i'm driving my car about 7-10km, the engine suddenly stop. Then, i try to start the engine, it seems too difficult. The engine has it cranked, and the battery is 12 volt. I already check the petrol flow and it looks ok. After 1 hour then i can start the engine. After that, i drive my car and about 7-10km it happened again. I really dont have any idea about this problem. Please help me.
