I've done the same miss 2 or 3 times. All on my Euro when the glow plug failed before a flight. All ended with flameouts after 2-3 minutes in the air. Luckily with a happy ending

The M160 has a hunger for plugs, so the solution for me was to add a "remove b4 flight" tag on the bung as you said + that I now always check that the glow plug works after each fligt by initiating a start after cooldown (you get a message on the Gaspar gsu if it's broke). Better to find out after a flight than just when you are about to fly standing in que at the flight line.
