Ice Experts – Head Unit keeps cutting sound??

[M@r]{]

Got a strange one here.  My Alpine Head Unit has got into a bad habit.  If I switch the car off, then back on again it looses the sound to all the speakers?  (ok with the sub)   If I then pull the connector out of the back of it, basically taking all power from it, it is then ok again??  Any ideas?  Is it some safety cut off?  Im not using an amp to power the speakers.
