Hey guys got alittle issue

So im driving back home from grabbing lunch, and once again my brant cuts off my engine, Try to start my car relise that the yellow indicator was not on. Not only that i take my keys out put them back in and the yellow indicator still did not come on, Lock/unlock my car and punch in my code Still the indicator did not come on.

In the end i had to take my keys out and put them back in, Turn the key back and forth and repeat the procedure till the yellow indicator would come on. In the end the car did start, however i am worried about the brant cutting my engine off again. For some additional information the car was started and driven for less then 5 minutes before it cut off my engine

Anybody any help or anybody who can shed some light? appreciated

Cheers
