needs more cranking to start the hotter the car gets

I have a 95 grand am with the 3100 v6 that starts up right away when its cold, but when it gets hotter after a good drive then it tends to crank for about 5 to 10 seconds to get it to turn on, but it will always turn on...I think the coil pack could be going...any other suggestion?

Possibly the coil packs. There are 3 on a V6, so if one were bad it would probably start right up but run rough for a bit. I would guess ignition module... but this is what testing is for.
