Emergency Help! 1.4 quicksilver is stalling

Hello, my car had a brand new engine. Before the engine was replaced, there was no such problem. The car starts and stops on its own, it doesn't matter whether it's hot or cold. After a while, the car stops, only after warming up, it stops with a bang. Sometimes, after running for a while, it doesn't start again. The throttle body was changed. The MAP sensor was changed. The idle motor was changed. The coil was changed. The fuel relay was changed. The injection and fuel pump were checked.

Hi, my 106XR engine was overhauled. Valve adjustments fixed it, but it was constantly stalling at lights, while driving, etc. It might be worth getting it checked.
