Problem in using MPC8260 in Master Mode

Hi,
I am using MPC8260 in master mode and the code is executed from flash at startup. The problem is that about 80% of the times the processor executes the code correctly and about 20% of the time it fails to execute the code. If the processor fails to boot from flash and PORESET or HRESET is asserted externally then it starts working again. A SRESET has no effect in this problem.
 
When the startup is failed then the MPC even does not toggles RAM_CS of FLASH CS. It is completely dead. The power supply sequence is correct. ANy suggestions in this problem will be of great help to me.
 
Waiting for your reply,
 
Thanks.
