Sudden crash while live streaming church service

OBS crashed during our church live stream yesterday. Any help would be greatly appreciated.

Live stream was running well. The operator was not touching the computer. The screen suddenly went black and both OBS and Chrome (used to monitor YouTube and Facebook conversations) went down. Upon restarting OBS, stream was able to reinitiate without trouble.

Checking the Windows Even Viewer, I see that the following warning shows up at 10:51:09.
"Display driver iqfx stopped responding and has successfully recovered."
This shows up 4 times within a few seconds.

This is the same time that the the OBS log states...

10:51:09.616: [qsv encoder: 'simple_h264_stream'] encode failed
10:51:09.616: Error encoding with encoder 'simple_h264_stream'

10:51:14.919: ==== Streaming Stop ================================================

Only other info is that our internet connection seemed to have some hiccups causing lowered quality. This is not normal, but it also didn't happen at the time of the crash.

Looks like the Intel graphics driver crashed, taking down the encoder (and OBS) with it, as you were encoding using the Intel QuickSync encoder.

It sounds like a hardware issue - this could be based on power delivery (the best way to do this is to use a UPS, as that'll provide clean, constant power), but also check what Power Plan is configured in Windows. It might be that the computer tried to go to sleep and was unable to, crashing the driver.

I'd also try updating the Intel driver: Downloads for Intel® UHD Graphics 620

I'm not sure why the log doesn't have a more descriptive error, or why it was unable to fully recover. It might be because the driver crashed more than once in quick succession.

Thanks for the help, WizardCM. The computer is on a UPS. I'll check the Power plan and look for updated drivers.

I verified that the computer set to never go to sleep or shut the screen off. I updated the graphics driver from the Asus website rather than from the Intel website in hopes that it would be better suited. We made it through the live stream last night without it crashing. Time will tell if this has addressed the problem. Thanks for the help.
