Upon hooking up the OBD scanner, I get a C0899 (Device voltage low), a C0561 (ABS disabled, invalid
serial data received), and P0673 (#3 Glow plug circuit). The first (and maybe the second) may be due
to low batteries, which I've treated badly this winter - only short trips to the store, etc. Trips
that should have been made walking or riding a motorcycle. So, the charger is on, and we'll see what
happens when the batteries are up to snuff.

"Glow plug" figured prominently in those threads I read about remote
start not working. It might be worth a shot. Does it run a little
rough for a minute on a regular start? I don't know a lot about
diesels but I am guessing if a glow plug was not working, it would
miss a bit until it started "dieseling"
It may just be a loose connection I guess.

Oh, and charging the batteries didn't change any of the readings. Looks like I've got an ABS problem
and a glow plug problem.

10 things to check:
Improper Starting Procedure
Vehicle Not in ?Park?
Too Many Remote Start Attempts
Coolant and Oil Pressure
Unlatched Hood
Hazard Warning Lights
The Key is in the Car
Check Engine Light
Dead Keyfob Battery
Check the Manual-

Regarding # 4 in your list:

For what it's worth my remote start will only work twice (two, 10 min.
cycles). A third attempt to remote start won't work until the key is
inserted and turned to "on" or after the truck has been started normally
using the key. After that the remote will work again for another 2
cycles. However, John has said that his remote will initially start
his truck but then it dies after a few seconds. That's not normal.

Mine will remote start (using my second key/FOB) if the other key/FOB
set is in the truck but not inserted in the ignition. I can also remote
start it using the GMC app that's in my smartphone. If I try doing that
with the key in the ignition, but in the "off" position, the app on the
smartphone comes back with a message saying, "Cannot start, key in
ignition".

Logic tells me that 4 or 8 could be the only things on that list
that could cause shutdown after start.

I'd narrow it down even more to #8. With the three codes that John's getting, it's hard to believe the CEL isn't on. Maybe the CEL bulb is burned out?

Don't think so. If he left his key in the ignition the remote start
wouldn't start the truck at all. However, it would if he just left the
keys sitting on the seat or console. Remember, John said his remote
will start the truck but it shuts down within a few seconds.

I did the same thing... don't count line #1, "10 things to check". #8 is the "Check engine light". # 7 is the key.
