In powering directly via the GPIO pins you are bypassing the voltage regulation (and fuse) that the Pi otherwise provides. You are therefore exposing the device to transients such as voltage perturbations. That means you need a good quality regulated power supply.

Quote from the article linked "It should be noted that, unlike the USB-C port method, there is no regulation or fuse protection on the GPIO to protect from over-voltage or current spikes"
The bold text is not mine, it is stressed in the link.
I think my approach then would be to power from the power port to see if that has any effect. Maybe using a power supply with the appropriate connector something like this one
That one is a 3A version but there are other similar ones if you think you need more capacity. It has a USB C connection so OK for Pi 4, if you're using a Pi3 then one with a micro USB is required obviously.
Good luck
