engine quit suddenly on interstate at 65mph going up a hill.

What is your question?

after stopping on the shoulder, the engine turned over easily, but wouldn't start and i had plenty of gas in the tank. engine was not overheated. tried in park and neutral with no luck. checked the fuel pump switch in trunk and it was ok. i pulled and reset all fuses related to ignition and also pulled and reset the relays in the power distribution box under the hood. about 30 minutes had gone by at this time and i don't know if that "fixed" the problem, but the car started and ran fine on the drive home. any idea what happened? i wouldn't like this to happen again on the freeway!
