Music pausing constantly over Bluetooth playing on the car

Thank you for your reply, it just happens in vehicles, yesterday I just realized that it's not pausing, the song minute counter bar continues playing, however the sound goes away (but as I'm driving I don't pay much attention to the mobile device) I found also that if I push pause and play on the car, the music sound comes back, if I don't do anything, the sound comes back until next song
