I can go 15 miles or 100 miles and when I turn the engine off it won't start for 30 minutes or more untill it cools down. I put a new coil pack on it and same problem. What do I look for next?

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing.
