First question is why you would let it idle for 15 minutes? Why would you need to?

I was moving all the wire to see it it was a loose connection

The first issue it was it due wen i was driving. So i try to see if some thing was loose and thats when i saw it die after few min of idle

take the carb jets out and push a wire through them to clean them out, especially the idle jet since its the smallest. make sure you have good fuel flow to the carburetor and that the float valve is working correctly
