Weird Bluetooth problem

For the last three days my Bluetooth has lost its connection from my iPad 9th gen. to my hearing aids. I have had the iPad for about 6 months and the hearing aids for several years and have used them for that time.
My Bluetooth on the iPad is turned on and, according to settings>Accessability>Hearing Devices they are connected as they always have been.
The weird thing is that for the last three days, early in the morning, everything works fine. But at some point it becomes disconnected with sound playing on the iPad. No matter how many times I try, it still says I am connected, but I am not. I have even tried Forgetting the Device and re-starting the iPad with no success.
My wife has a Bluetooth enabled device that she has been using for months with no problem interfering with mine.
Any suggestions?
Thanks.
