remote xBee stops working in loopback after a couple of seconds

Hello again,
I've started working through chapter 5 of Programming and Customizing the Multicore Propeller Microcontroller and successfully got two xBees to communicate using the loop back and even did a range test. Everything worked great. However, when I came back after lunch -- exactly the same setup -- the remote xBee configured for the loopback, using the prop stick for power, stopped working correctly.

I have the local xBee connected to the computer using the USB adapter board and I've tried this with all possible combinations of all 3 xBees I have, and it appears to be a problem with the remote setup/configuration, not the xBees themselves.

What happens is, after hooking up power to the remote xBee, the red light blinks consistently and the yellow and green lights go steady. A second or two after that, though, all of the lights begin flickering extremely quickly (to have the appearance, occasionally, of all going steady, but upon moving the xBee around, one sees they are flickering at very high speeds). Sometimes I am unlucky enough that it just starts off flickering quickly when I connect power to the system, too. It is not a consistent amount of time before the flickering begins.

If I run a range test or loopback (while typing) the remote xBee works properly when the lights are how they should be. As soon as the high speed flickering starts, however, I get a timeout in range test or no more echoed typing.

What confuses me the most is that we did nothing to change the setup which worked perfectly before lunch.
We've tried using a different battery, and I don't expect that to be the problem either.

Please help!!
Thanks

    The flickering also appears to speed up as it goes on until all of the lights appear to be steady.

    Ugh. Of course, using a steady 3.3V DC power supply (from a DC generator) it works.
    Must be a problem with the battery...

    Ignore me!
