Hi @Zamu, sorry to hear about this. 
I have translated your question to English as this is an International forum.
It's hard to say what the cause is before we do some troubleshooting. To start with, I would recommend that you try with a different SD card in your device and see if that is also disconnecting as your current one is doing.
Let me know how it goes!
