Car doesn't start on warm days

[alecxis_j30]

After driving it for about 15 minutes it won't start. Only on warmer days though.
Engine turns on for about 1-2 seconds. Then dies. Then after 20-30 minutes it'll start like nothing ever happened.
Did my research and found most of the time it's main relay. So I bought a new one. Same thing happened. Just replaced the main relay yesterday and then it happened again today.
Any input will help!

MIL/CEL, code #?

Search up the ignition switch recall and see if you have any of those symptoms. Usually if it's related to hot weather it's the main relay though. When you turn the key to position II, do you hear the fuel pump prime?

No cel or mic. The fuel pump does hiss (if that's the sound). It's really frustrating cause it only happens sometimes. Let me look up that recall.
Thanks for the quick response!

Fuel pump should emit a faint but audible "whine" for a few seconds

Well it just made the whine sound, but the car also turned on.
