The Query Just Stops - At Different Places

I have created a stored procedure in SQL Server. I found it very slow, so i putted "select getDate(), 'testposition 1'" at different places, so I could see what part of the code that takes time.

The problem is: Depending on where I put the select statements, the execution of the stored procedure seems to just stop. And depending on where i put the select statements, it stops at different places.

This is how I do (example):
1. I re-create the stored procedure with some "select getDate()"-statements
2. I run the stored procedure 15:00:00
3. I cancel the stored procedure after 20 seconds and look at the resultsets. All getDate-functions show a time between 15:00:00 and 15:00:02
4. I run the stored procedure 15:01:00
5. I cancel the stored procedure after 5 seconds and look at the resultsets. The same amount of resultsets are showed, so I can make the conclusion that the execution stopped at the same place as last time. All getDate-functions show a time between 15:01:00 and 15:01:02 this time too.
6. I re-create the stored procedure with some new "select getDate()"-statements
7. Now the execution stops at an other position. Somtimes even between two "select getDate()"-statements!

I pasted the whole stored procedure here:
