Codewarrior programming MC56F8367 gives Unknown protocol error

I have been developing with Codewarrior for about 7 years, and we have (finally!) got into production. I received 10 Cards which have the MC56F8367 DSC fitted, and began to use Codewarrior to program each with our latest firmware. 6 of the boards programmed fine, but 4 of the boards did not. Codewarrior reported "Unknown Protocol Error". My Codewarrior version is 8.3 (build 091203). Anyone got any ideas as to why this might be happening?

This is the error message you get if you do not supply power to your board.

I have never seen this error message in other circumstances.

However, if there is an electrical problem on the JTAG interface, it could give this message.
