Why did some american leaders call for a stronger national government ?

Assuming you are speaking about when leaders wanted to reform the Articles of Confederation -

The current government was incapable of settling national disputes without any money from taxes. This included many interstate issues, such as taxes on trade and even states denouncing other states. With a reformed federal government, they would be able to step-in and maintain order within the country.
