If you had reported those two situations without other new ones the #1,2 and 3 most likely candidate of failure would be the ignition switch.

It's nearly 100 chance of what caused the problem for the exact thing you did; tried a couple times and after I took out the key and tried again it started. That's the exact symptom of a failing ignition switch
