Honda city engine swap

I have recently changed the engine of my honda city idsi 2007 model from L12A to L15A. After changing engine, the car get started on first try. It remains OK in idle position but gets switched off during driving every now and then. What can be the problem? What options do I have?
Thanks for reply

Thanks for your suggestions.

Problem rectified. Throttle body and fuel pump were faulty and are replaced.
