Reloading sounds after away periods

Sej22

When using my Native Instruments sounds, either through my DAW (Logic) or the dedicated Komplete Kontrol or Kontakt 8 apps, if I have a break for a few moments, the sounds appear to need reloading?

To make it clearer; I'm playing and everything sounds great, I take a break for a minute or two, come back I play and the sound won't play properly for a few seconds, before working as normal.

When I'm at home and trying to record/rehearse, that's fine and it doesn't bother me. However, I'm trying to use my Native sounds for live uses and if I don't play for a few moments and then I have to use it, it can be very problematic.

Any advice?
