Do as Carlo suggested and pull the logs. But what machine are you on? I have a 2015 Macbook and it has the same issue that seems to be an issue with the Mac hardware itself. Sometimes I can go for many hours without issue, other times I cannot even work for hours unless I just pull the 2nd monitor. In my case, its the USB3.0 bus dropping on my HDMI/AV adaptor connected. It resets, then it comes back, then it comes back on.
Some suggestions were to run some sort of USB 2.0 cable between the macbook and the adaptor but I've not found anything that seems to fix this issue. I've just stopped using my Displaylink devices at this point.
