Default Hard to start when engine is hot

Usually I will turn off my engine when i'm parked waiting for someone so i don't waste gas
but recently i've noticed when my engine is warmed up doesn't matter if its night or day, it seems to be hard to start.. sometimes it feels like the engine will stall, or it will die out and i have to start the ignition again, but it starts up fine after

kind of sounds like its cranking longer then starts

when the engine is cold, its fine

i have a tune up planned but im wondering if the ignition coil is getting too hot

or do i have to change out all the coil packs too when i do a tuneup?

also anyone have any way to test rear window defroster? it doesn't seem to work.. the lines but i'm not sure.. i really hope my tint guy didn't cut them

Clean out your air intake - MAF Sensor and the IACV. Those parts are such trouble makers that you just have to try them first. Make sure you only use the CRC spray on the MAF.

I used to have a similar problem. I ran a bottle of injector cleaner (Seafoam) and it solved my problem.
