Could also be a stuck precharge relay, or something wrong in the precharge circuit.

like the likely culprit.  What is the Zilla measuring that is causing this 
error?  What should I check to clear it up?  It usually only happens when I 
first turn the truck on, but I have noticed that when sitting idle for a long 
time occasionally the truck refuses to move or the main contactor drops out all 
together as well.  It has not happend at a stop light or similar stop, only in 
my driveway or when waiting at the curb for a long time while picking up my 
daughter.

So, it's probably seeing pack voltage when it thinks it shouldn't be.
