Step-thru stored procedure ends prematurely in Visual Studio

I am able to step into a stored procedure from my C# just fine, however, the step thru ends prematurely.

From Visual Studio, I step thru a few lines in the stored procedure, then as if the connection timesout, execution leaves the stored procedure and returns back to the C# code without letting me complete my step-thru the entire stored procedure.

How can I fix this so that I can complete my step-thru the entire stored procedure?

Thanks
