DF2301QG V1.0 stops working after a while ( few minutes ) needs reset to work again, why?

The DF2301QG V1.0 Voice recognition module works well after a reset but stops working after a while not the same time, sometimes a few minutes is enough , it does not respond anymore to the wake word until I reset the module.

The module is connected to an ESP32 and is running below program:

What can be the reason/solution? Other people have this problem too?
