KL82Z - JLink doesn't work in STOP mode

For measuring low-power current draw, I programmed an application into KL82Z flash that immediately puts the device into STOP, via POWER_SYS_SetMode().  However, now I can't re-program or erase it.

 

JLink fails to connect with the attached errors.

 

I've also tried booting the KL82Z into ROM bootloader and running `blhost`, but that doesn't seem to work either.

 

Is this expected?  Is there any other way to recover the device?

 

I'm using KSDK 1.3.0 for KL82Z, and have a JLink Base.
