I'm away from home at the moment so I don't have access to the Pi. I'll certainly have a look to see if I have the logs still when I return.
The PSU that I am running is the Official UK Raspberry Pi 4 PSU (5.1v, 3A) into the Argon One M2 case. I see that Argon do their own PSU which is rated at 5.2v and 3.5A which might be worth a try?
