PT2000 Dev brd stops working

I'm using the PT2000 programmable Solenoid Controller Gate Driver eval board with a 24V battery supply. I've upgraded the devices n the board to handle 24V system.  It works for a couple of minutes and then suddenly stops communicating. I have an external VCCP and the VCCP_EXT_EN register set to 1 as explained in the datasheet. After a couple of configuration attempts the chip stops responding to SPI commands and does not recover.

Anyone have any ideas as to what may be wrong??
