Seeing very strange behavior.... Is a reset is required after an erase cycle?  Also, the reset sequence uses an 8 bit "reset enable" CSHigh slight delay CSLow 8 bit "reset".  I'm using SPI in 16 bit mode. 
- Do I need to change my SPI interface to 8 bit for the reset process? -Thanks
- Is it possible to very a software reset was completed correctly?  It's very strange I can successfully program the IC 7 times and it fails on the eighth cycle.  It's actually random but the concept is the same....

Closure -
The issue has been tracked back to the PCB coupling signals through a poor power plane.  Also, 8 bit commands appear to be working fine using a 16bit word or 8bit command byte. :)
