"Hard Reboot Restores iPad Charging Temporarily: Ok, but what do you do when it’s not the iPad port, it’s not the cable, and a hard reset works to start charging again, but only lasts a few minutes before charging stops again and needs to be rebooted?"

Troubleshooting iPad Charge:
A. Start Here: If your iPad won't Charge - Apple Support
B. Which Cables to Use: iPad Accessories - Power & Cables Power & Cables - Apple
C. Try what is on these Links:
D. Use an Apple Brand Cable:
Do not use a third party cable - cool though it may look, a fabric, third-part cable would likely tear - (Apple cable's are plastic and are intended for Apple).
E. About Battery Health:
Apple doesn't have Battery Health on an iPad. But, for note, Apple recommends that you get a new battery on an iPhone once its Battery Health reaches 80%.
F. A Faulty Device?:
So, is this covered under warranty? Note that this comes with a one-year, out-of-the-box, limited-warranty. So, set up a Genius Bar Appointment, asking them if this a faulty device.
