Cut offs can happen for a number of reasons, the software isn’t really coping maybe.
If you have wifi and network on it can switch between the two
If you have bluetooth enabled and the wifi is using 2.4Ghz there can interfere as they used the same frequencies most often.
If you have bluetooth and network on 4G again there can be a cross over due to frequencies.
So if the software is not good enough it may ‘cut the connection’ and not re-establish it promptly.
You can look at the frequency issue and maybe turn off bluetooth and wifi if you don’t use them 24/7
