Shuts off while driving. on 1999 Mercury Mystique

My 1999 Mercury Mystique just shuts off while I am driving. If I let it sit for a while, it will restart and run like nothing ever happened. I had the coilpack replaced because my mechenic said thats the only thing he suspects. The computer shows no faults. Whats wrong?

I would check the crank sensor and the ignition module. The coil pack usually fails 1 cylinder at a time.
