Unable to connect to OM13084 using MCUXpresso 10.0.2

I'm unable to reliably connect to my OM13084 development board with its LPC43S67 chip.

 

With a brand new board, I was able to connect and debug periph_blinky and other programs successfully.  All debugger functions seemed to work.  The session lasted for a couple of hours.  I powered down the board and went home for the evening.  The next morning, I was unable to connect to the probe.

 

When I rebuild the project, MCUXpresso detects the probe (with proper version number and serial number) and the build step completes.  At the end of the build, I get a pop-up saying that no JTAG probes were found.  Nothing changed since the previous night.  The board was depowered and unconnected.  This behavior has been observed on two different new boards now.  Once the pop-up occurs, I'm unable to recover.  I can never get the IDE to connect to the probe.

 

I've been through the probe troubleshooting steps in the User Guide.  Anybody have any ideas?
