Electrical problems

I have Yeti 2.0 TDI 4x4, manual, l. 2011, few months ago background  lights of tachometer start to blink, lately when I drive for at least 30 min, complete dashboard goes dark, tempomat stops working, rear parking sensors stop working, back speakers can not be seen on radio although they are working, also all 4 windows do not go down. After I stop wait a bit everything starts to work.

Did anyone else had same problem?
