Unresponsive Kinetis

I find my K20 unresponsive from time to time. The device should be running continuously, but it seems to halt. Then when I hook a JTag to the chip I am unable to read memory or view any state.

The only way I can recover the K20 is by power cycling the chip right before i try and re program it. So I have no way of determining how it go into this state. Not even the WDOG resets it.

What could be happening? And ideals ?
