IPod Touch will not restore in iTunes

Question

My iPod Touch keeps switching itself off suddenly and as instructed I hold the top/bottom buttons together and it usully comes back on.  But, now it will not hold and just keeps switching itself off and on.  A couple of times it showed the apps etc. but then switched itself off again.  I have now managed to get the "plug into iTunes" picture up and each time I manage to get this and iTunes acknowledges it I try to restore it but it gets so far and the iPod shuts down and it shows that it cannot be restored.  A friend has also tried to restore on his computer but gets the same problem.  iTunes is up to date and when I originally tried to update the iPod as requested it would not do it as iPod again shut down.  Can anyone help please or do I need to go to an Apple store to get a repair.  Thanks

Answer 1

Thanks for that.  I have already tried this exactly as written.  I get half way through the restore and it freezes and tells me that iTunes cannot see the iPod and the iPod has turned itself off again. I have tried doing this procedure for about 2 hours and so has our friend on his computer but the same thing happens.
