This is not an answer to your post but a similar experience I was having with a GTX 1070. I would lose video output for a few seconds and it would occur several times before it stopped. Sometimes I did need to restart my computer to get everything working normally again.
But don't know if it was a GPU Driver update or a Windows 10 update but the problem hasn't occurred anymore in a few months.
I would try installing the latest AMD APU Driver from 04/03/2019 from here: AMD Ryzen™ 3 2200G Drivers & Support | AMD
If that doesn't solve it, try installing a older previous driver in case it is caused by the newer AMD Drivers from here: AMD Ryzen™ 3 2200G Previous Drivers | AMD
Also open an AMD SUPPORT Ticket from here: Online Service Request | AMD
Run DXDIAG.exe and export the .txt file. Go to the last category called "Diagnosis" and see what files (programs) are crashing or having problems. It might narrow down your troubleshooting procedure.
