IT sounds like an ALTENATOR problems. The altenator charges the battery which gives energy to all your electronics and keeps your car on when at a stop. If the altenator is bad, it won't charge the battery and the car will keep dying at complete stops and eventually wont start. Because u got a foreign car (not sure though), it might cost u a little more to buy an altenator and have it put on. it'll probably b like 100.00 for the part and around 50.00 for labor depening on who and where you go.
