Q: New beetle dies while driving but starts back up

First of all I want to sincerely thank whoever takes their time to help out someone in need. I truly appreciate it. My problem started when my husband took my car to work. He drives on the freeway and he reached his destination and when he stopped at a stop sign the engine stopped working. Everything stayed on, like the radio, lights, etc. But the engine. So he turned the key back and started the car again and it was like nothing happened. He checked the battery fuses and they are fine. He drives back home, takes the freeway and merges on the exit and before he makes a full stop the car dies again. Again, he started it with no problem. He gets home and before he does the car dies. He tries to start it again and this time she doesn't start. No cranking noise, no sound or smell whatsoever. So ever since that one time, the car turns over fine. It still dies while driving. What can it be? Crankshaft sensor? Camshaft sensor? Fuel filter? Injectors? Please help me out. I sincerely appreciate
