Golf 4, engine cuts off while cruising and starts again.

Ok, third problem of the day. This problem is very intermittent. Happens maybe only once every month. While driving the engines just cuts off for no reason and starts again. Any help on this would be very much appreciated.

Hi, i have had this problem before. I rectified this problem by removing a lot of my keyrings from my keys. I had a fair weight on the key, and sometimes it would pull the key back just enough to stop the engine? I also had this problem with a Mk3, but this was the fuel pump relay switch? No idea if those suggestions wil help, but they worked for me.
