Hi everyone, wondering if anyone has run into a similar issue

When I dont start the car for a few days, or its very hot outside, car will be hard to start.

If I leave in garage covered, issue wont be so bad.

Yesterday I was driving for about 2 hours, going up a high incline in the mountains, outside temp was cool. I shut car off, and tried to start after 10 minutes, and same issue, hard to start and a bit of a rough idle after.

Any ideas please?
