I am powering down my arduino with SLEEP_MODE_PWR_DOWN and it randomly wakes and starts back at the setup loop. Any ideas on where to start? I hooked up a multimeter to the Vin pin to see if there were any random spikes but it didn't drop below 3.3v.

How frequently? Every millisecond? Minute? Hour?
