LPC43xx 200MHz issue

I am running a LPC43xx @ 200MHz


Occasionally (not very often), the PLL does not lock during power up and code stops when switching over to the PLL clock.


I have tried stepping the clock to 100MHz then to 200MHz as per everything I can find, but it doesn't work.


External 11.0592MHz Xtal.
