So why are you acquiring continuously at 1kHz????

Yes, I tried to use other moder acquisition, but it also hangs. I'll try VI Time Lapse to determine the acquisition, thank you.

Then you should attach that attempt.  As a VI we can inspect and not just a screenshot.

You don't want to have a hard delay of 30 minutes in your code.  Depending on how you wire it up, if you want to stop your VI, it might take up to 59 minutes 59.999999 seconds for your VI to stop.  Your VI will appear frozen during much of that time.

What would be an alternative to my data collection?

All you need is a simple state machine that monitors user interaction and elapsed time at a reasonable rate.
