Hey Ken
Sorry to hear this, but I possibly have a soloution for you, mine was doing the same thing, 1st lemme get some info....if you reset it (use a paperclip or pen to press the reset in the top left corner of the units face) will the unit restart? this is what mine would do.I lived with it for a year or so reseting it everytime it would shut off, sometimes it would stay working for 3 days or so and sometimes it would go out instantly!!!
I looked into sending it to pioneer (then it was $200 flat rate service ,now its 230), i waited too long i guess.
  I finally sent mine into Pioneer and they looked at it and had to replace the Nav unit inside, it cost me $230 flat rate and they pay to ship it back to you.

i sent it in on march 20th 2012 and they fixed it and have shipped it back as of the 28th

another question ; for navigation discs did you use original or copied discs? the only reason i ask is i used copied and wonder if that is what went wrong (as crazy as that sounds)


good luck

Mike
