CC2630: Clock only works during debug sessions and after CPU reset

Part Number: CC2630
Other Parts Discussed in Thread: CC2650, TIMAC, UNIFLASH, , CC2651R3, SYSBIOS

I am working with TIMAC (tirtos_simplelink_2_11_01_09) and trying to write a simple app that blinks some LEDs. This program works as expected when during debugging sessions but when I disconnect power and plug back in it will fire a single timer event then freeze. If I go into Uniflash and issue a CPU or System reset the LEDs blink as desires. If I issue a board reset the LEDs never turn on at all. I'm working backwards from the msa_cc2650 example app so there is a lot of bloated code here, but the relevant portions are

Void main()
{
  Task_Params taskParams;

  // set RFC mode to support IEEE802.15.4
  // Note: This must be done before the RF Core is released from reset!
  SET_RFC_MODE( RFC_MODE_IEEE );

  // enable iCache prefetching
  VIMSConfigure(VIMS_BASE, TRUE, TRUE);

  // Enable cache
  VIMSModeSet( VIMS_BASE, VIMS_MODE_ENABLED );

  /* Initialization for board related stuff such as LEDs
   * following TI-RTOS convention */
  PIN_init(BoardGpioInitTable);

  // Configure task.
  Task_Params_init(&taskParams);
  taskParams.stack = myTaskStack;
  taskParams.stackSize = MSA_TASK_STACK_SIZE;
  taskParams.priority = 1;
  Task_construct(&myTask, taskFxn, &taskParams, NULL);

  BIOS_start();     /* enable interrupts and start SYS/BIOS */
}
