If pushing down on the CT60 makes a difference, this is odd since the bus connectors would seem to make very good contact and not be succeptible to being unseated easily. Could there be something else affected by this pressure?
Is it possible that there is a broken solder connection somewhere? I have seen that kind of temperature related problem where a solder joint or pad is cracked, causing the circuit to be broken as temperature fluctuates. I have also experienced one case where a miniscule fleck of solder was causing an intermittant short. You might want to inspect carefully with a magnifier if you haven't already.
Otherwise, I would probably try using a fixed oscillator to verify the stability of the entire system, so you can be sure the cause is specific to the CTCM. You might want to get two oscillators, one for the stock speed (50mhz or 66mhz), and one for the speed that you normally use, that way you can test both for heat related stability.
Best Regards
