MCF51JM128 device doesn't run without programming adapter connected

I'm using a P&E Micro USB Multilink Universal programmer to flash and debug a MCF51JM128 (64pin) device.  I have no issues flashing, debugging, and running the program as long as the programmer is connected, but the program doesn't run otherwise.  If I get the code running and then disconnect the programmer it continues running, but if cycle power or reset it, the program stops.

 

I have 10k pull-ups on the BKGD and RESET lines, and the oscillator runs normally, but it just doesn't seem to start the code.

 

Are there any suggestions as to what I might try here?

 

Thank you
