Do you have the same issue if you follow the OP’s steps to reproduce it?
No. The OP doesn’t list any steps or aircraft. While I haven’t tried all aircraft, the stock C172 and all my add on aircraft do no have the issue.
I’m wondering if it is simply battery exhaustion due to the alternator(s) not being on but I know that is well documented.
