If it is the explore 100 version, pin 70 is SPI so shouldn't be connected to reset.
Connect to the reset alone and leave pin 70 free to do it's own thing...
The explore 100 has an optional reset circuit included to cater for slow power supply rise time and brownouts.
If your system doesn't' have that addition, now is the time to fit it.
As a final protection, once the external issues have been fixed, use a watchdog in your program, but fix the problem first, or at least, record when the watchdog is activated.
