Heatsoak is when your engine gets hot and will heat up your intake (or supercharger, if you have one). This means the air going through your intake gets hotter, and when its hotter you make less power because the air isn't as dense. Really the only way to get rid of it is to let your car sit and cool off. This is why when you drag race you should wait 20 minutes between each run so that your engine has time to cool down.

Soccerluvr4 is most of the way on track. The reason you make less power is because the engine pulls timing. When you IAT's get to high your ecu will ****** the timing to prevent detonation. As long as you keep the car moving IAT's won't get too high but once you stop at a light on a moderately warm day it'll really set it

Seriously doubt that is whats causing your starting issue. Heat soak will cost you some power if sitting in bad traffic or at a long light, like grabber already told ya, but all it does is pull timing, it has nothing to do with the way the car starts up.

Have you checked the relay and fuses for you're starter? Maybe its on its way out the door, or you got some condensation or residue on it, and at times limits the contacts.
Also could be a bad ignition switch.

Like i said, check all the basic stuff first. All your fuses and relays (inside and outside of the car) for the starter, and ignition. Also check to make sure your battery and battery cables are secure. A loose connection, or a fuse/relay with a not-so-clean blade will cause this.

My car used to have the same starting issue. It wouldn't want to start after some driving, that was when I first got it and was putting 87 octane in it. I filled it up with 91 and a can of seafoam and it rarely does it anymore, and if it does then its not nearly as bad as it used to be.

You should do a tune up to your car. So check all your fluids, maybe some seafoam, change the oil filter, fuel filter ect... That would be the best way to start.

A tune up wont hurt at all, but with only 24k i really doubt thats the route of your problem tho. Keep us posted man, we will try and help you out as much as we can. Make sure to check your ignition and starter fuses/relays!
