Fuse+ USB stops after 1 minute

Just purchased a Sansa Fuse+ 16G, When I plug into the USB screen indicates connected. It will be OK for 1 minute or so, then the screen goes dark and I loose the USB port (Fuse icone gone from media player). If I pull the cable & wait 20 sec or so, then reconect, the Fuse+ comes back to life. I have bone the firmware upgrade but it did not fix the problem. Some one on another page said to try holding the Volume down, it did not work. I am trying to set the SLEEP & powersaver to 120 minutes. It lasted 3 minutes then went down. 

Anyone have any ideas?

Today I tried another cable. It’s better but not quite there

Does anyone have any recomendations?

I’d contact your dealer or SanDisk directly about a possible replacement. It sounds like a defective unit.

Have you tried another computer? If it acts the same way, I’d contact your dealer or SanDisk directly about a possible replacement. It sounds like a defective unit.

Yes, i did

First on my wife’s Compaq Laptop, then on the family’s Gateway tower. Both are on W7

I do find it strange that there is a difference in performance depending on the cable?

The problem seems inconsistent but the OEM cable is much worse.
