Ignition Coils Failure problems of the 2005 Mazda MAZDA6

Had 30000 mile service done prior to a 1000 mile one way vacation trip. After arriving at our destination washed car at coin car wash. Drove car for about 10 minutes and engine began surging, transmission would not move from second gear, and vehicle speed would not exceed 20 mph. Exited roadway and parked vehicle overnight. At engine startup vehicle ran fine but with engine light on. Drove 60 miles and vehicle suffered complete shutdown on freeway. Vehicle coasted to a safe stop and called Mazda roadside. Vehicle would not even turn over. Vehicle towed to dealership, ignition coil and pcm were replaced. Dealer approved vehicle for 1000 mile return trip. After only 4 hours of driving engine light came on again. Exited interstate, parked vehicle and called Mazda roadside. Vehicle currently under repair. This was two identical failures within 200 miles of use.
