I’ve dealt with numerous iPads doing the same behavior.
 
Unfortunately, there is no one solution for all. It really could be charging port, Tristar, battery, PMIC, or any combination of the above. I even had one that I could not solve despite replacing all the above, unless the PMIC I used was defective because it was warming up and I had no other spare parts. Those PMIC are pretty expensive by the way and replacing them requires a fair amount of skill.
 
The PMIC integrates charging in iPads, by the way. So if “Tigris” is misbehaving, it is actually the PMIC.
 
It used to be very seldom the PMIC. Now I am starting to see more and more of them. I guess they are starting to die more frequently after all this time in operation.
 
I think the numbers you listed could point to that. But you need to rule out everything else first.
