Hero Motocorp — hero duet starting problem

I am experiencing a bizarre problem with my new hero duet scooter. It starts fine in the morning, moves around well after the engine warm up... But fails to start after a short stop. Usually, i switch off the engine if i am going to purchase groceries in the middle of the journey. After that scooter fails to start either by electric start or kick start. It does start after few minutes. I bought the new hero duet in march 2016. I visited service center and highlighted the issue, but the problem was not solved in the last service also. They increased the idling, but the start when required is still a major issue. Is this a common problem in hero duet? kindly help me to solve it.
