I've seen this kind of bug occur on other laptops, and in those cases it was a hardware fault (the ribbon cables for the keyboard and touchpad randomly lose contact).
For the moment let's assume your case is still a software problem. So can you please try:
1. Booting 16.04 and use it for a while. Does the problem occur there? https://www.ubuntu.com/download/desktop
2. Booting 18.04 and use it for a while. Does the problem occur there? http://cdimages.ubuntu.com/daily-live/current/
3. Does installing older or newer kernel versions fix the issue? kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
