Check Engine Light On problems of the 2014 Ford Fusion Hybrid

I was driving my Ford Fusion Hybrid today on the interstate and had a complete engine failure while driving. I was driving, then a noticed popped on my dashboard stating to stop safely now. I pressed the gas pettle and the ev mode kicked on, propelling my vehicle speed to over 85 miles per hour. I was extremely nervous because the Fords electric vehicle engines are limited to 85 mph in pure ev mode. I was able to come to the shoulder of the interstate. I turned the vehicle off, waited a few seconds and restarted the vehicle. All seemed to be ok, as soon as I pushed the gas pettle to get back on the highway the information dashboard was alarming me to stop safely now. I did not have any check engine lights come on. I then revved the engine to see if I would experience anything, the engine finally came on, then revved and I felt that even though I was in park if my foot would have been off of the break pettle my vehicle would have moved forward. I turned the vehicle off as soon as I felt this the engine was constantly revving until I turned the key to the off switch. I then had the vehicle towed to the dealership. I was driving at 76 mph on the highway and complete failure occurred.
