Vehicle starts and runs like a new one when cold. Hard to start and ignition seems to stick when warm

What kind of poll is this?
Crank sensor is possible but the poll makes ZERO sense.

Since it is a poll: I vote ignition switch . . .

. . . at least until I know more about what "hard to start" means.

The obvious answer to "What causes warm engine to not start"
Chose box "engine hard to start when warm"
Yikes. I don't think we are playing with a full deck.

I voted for both.

They didn't have enough choices though, such as:

- Rod through side of block
- Sodium silicate in crankcase
- Battery with hole in it

Either way, we need a better description of the "hard to start" part. I'm guessing the choice to make this a poll was accidental.
