OK, so we actually had a bad cell that shorted the 12volt battery.
replaced under warranty today. Car works fine.
The intermittent warning message "Service EV System, no power" lists several different possible causes in the owners manual.
None of them were that the 12 volt battery might be bad.
We followed the procedure below, and then the car worked.
We replaced the batteries in the FOBs and then the car worked.
The last time, we were in a parking lot, and the warning message appeared.
I went back in the building to use the bathroom after calling AAA for a tow to the dealer.
When I came out and tried to put the car in neutral for the tow truck -- the car worked!
I cancelled the tow and drove straight to the deal.....about 0.5miles.
They replaced the battery at a value of about $400-$500.

Thanks to henrydehoja I was able to identify operator error.
We charged 2019 Leaf SL PLUS for 3 hours last night on timer, however I forget and left my fob in the cup holder.
The car is my wife's that she drives most of the time. In the morning, I removed my fob from the car and placed back in house.
Later, when she went to drive the car, "Service EV System No Power" error.
Thanks to this post from Oct. 4, 2018 by henrydehoja I was able to follow his procedure, holding my wife's fob in the car and leaving the other fob in the house. Avoided a tow to dealer! Avoided down time without car!
Thank you henrydehoja!

I have not seen that on my 2018 Leaf. However, it sounds like it may be an issue with the vehicle immobilizer system. Below is what I see in the manual on this system:
NISSAN VEHICLE IMMOBILIZER SYSTEM
The NISSAN Vehicle Immobilizer System will not allow the power switch to be placed in the READY to drive position without the
use of the registered key.
If the power switch fails to place the vehicle into the READY to drive position using the registered key, it may be due to interference
caused by another registered key, an automated toll road device or automated payment device on the key ring. Restart the
EV system using the following procedure:
1. Leave the power switch in the ON position for approximately 5 seconds.
2. Place the power switch in the OFF position and wait approximately 10 seconds.
3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to drive position while holding the device (which may have caused the interference) separate from the registered key.
If this procedure allows the power switch to be placed in the READY to drive mode, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices.
