TVS Motor Company — Tvs jupiter engine

Address: 635126

I have purchased a brand new tvs jupiter on feb 2017. The bike have run 1800kms. The problem with the jupiter is that when ever i throttle hard or accelerate hard the engine slowly looses power and comes to halt after 5 mins of high power ride and the engine also gets over heat with just 5 mins of riding. The under seat stirage also gets too hot.
Only after some minutes of cooling down the engine starts. This happens every time i ride hard and fast.
Why this happens. I expect a reply from tvs company since i had great trust over you guys. Plz dnt let me down on your companys trust.
