Yes, I have the same problem of automatic shut-offs. They can happen as frequently as 30 seconds apart or 5 minutes apart. There does not seem to be a pattern to the timing. This problem only occurs while playing from a docked unit. It happens in my iHome as well as my DICE hard-wired car connection kit (which has a docking cable). When played through the headphone jack, everything is fine. This problem only surfaced with Firmware 1.0.2. However, the older firmware did not work well with iHome, as it would not respond to commands to turn on, wake up with alarm, etc. Also note that this problem occurs whether issuing play commands from the iHome remote control, the iHome unit itself, the iPod 3G Nano itself, or my car's radio commands (as passed through the dock with the DICE unit). Apple, when are you going to fix this problem? Hopefully before I return my iPod!
