Of course not. That's because execution is in parallel between the top portion of your code which goes to the pause loop and the bottom part of the code which builds a bunch of arrays.
Another thing is that you want the Pause button to become visible only if the time delta is between 25 to 30 seconds, which will only occur once maybe twice depending on how quick you press the pause button.
You should consider using a State Machine to implement your solution. You would have a "pause" state, that basically does nothing except monitor a change of state of the pause button which affects the next state.
You can find many examples of state machines on this forum.
To learn more about LabVIEW, I suggest you try looking at some of these tutorials.
