97 Celica GT 2.4 hard or no start afer driving around and warmed up.

Hi, I hope someone can shed some light on this, my 97 Celica GT runs fine , battery is solid, no fuel delivery issues, timing is good, no backfires, new air filter, but when I have been driving around for like 20 mins and park for 15-20 or so I have trouble starting up, I have to keep trying and eventually it will kick in, but last night when I got home I tested it by letting it sit for about 20 mins and tried to start no dice, tried few times, then after cooling off over night, it started right up today with no problem. I remember a mechanic that was working on it said it could be a IC chip that could be overheating, but I have no idea if it is where it is, I'm also concerned that it could be an engine or ignition component that is overheating and once it cools it's easy to start, any one have experience with this or could give me some idea of what it or could be? I did a search online but came up empty.
Thanks

crank no start or no crank no start?

Crank no start. Could it be the ICM?
Thanks

2.4? Do you mean 2.2?

Sounds like a bad ignitor to me

Classic bad coil symptoms.
Start by checking/replacing it.
