I have an expensive gaming keyboard

Basically the issue is after a while of playing FFXIV, a large section of the keyboard locks. All software is up-to-date. I have to restart my computer before it starts working again. If I'm pushing a button when it locks, it will act as if I keep my finger on that button (makes it fun trying to restart if the last button I pressed was the Enter key)

Anyone else have this issue? it only happens with FFXIV.
