Honda 2 Wheelers India — Cb shine sp 125

The bike engine stops working in running condition anywhere.The compressor loss, after 1 hour or many try it could start again, it repeats.
My bike i have purchased on january from ahmedabad.
After 8000 km engine problem occured in it, after complaint gopalka honda (dhanbad) changed the head and convinced the problem will not raise again.
But after 16000 km same problem occured in engine. Now sandhya honda (bokaro) misguiding me.Service manager([protected]) & devi honda (chandrapura).
I want a proper solution with clearification from honda, other wise replace the bike engine or bike.It not occurs in normal engine, there is a big fault in the engine of bike.This type of fault can cause big accident on road(accidently engine stops)while running .
