The best recommendation for now would be to code things so there can be a recovery to having things work as required if the PICAXE resets.
Thanks Hippy for this confirmation.

I assume that either you or Technical ran the program that I posted back in #2 and found that a bare 08M2 fitted with only the 2 programming resistors and connected to a power supply did reset at an interval of about 7-8 minutes?

Thanks to everyone for their contributions.
