I would like to ask you some help on keyboard Roland GW8L

I have this keyboard but twice now it comes in confusion to play alone, blocks buttons, records sounds edit sounds etc ...
After + - two days he returns to stabilize . It has something to do with rhythms and songs that put the keyboard memory ,or can be Keyboard power ?
