Electrical Jack problems of the 2013 Honda Civic

On 22nd March 2014, I was driving my one year old Civic on interstate 55 from jackson towards baton rouge. After travelling about 50 miles with an average speed of 65 to 70 miles per hour, I suddenly faced problem with acceleration. The acceleration went crazy spiking the tachometer between 4000 and 6000 rpm and the car was slowing down though I gave the acceleration. When I gave the acceleration, it was making roaring sound and rpm on tachometer is spiking between 4000 and 6000 rpm. Car was coming to stall slowly from 65 mph, before it could come down to standstill I turned on emergency lights and pulled the vehicle on to the shoulder. Fortunately two vehicles behind me past my car merging to left lane seeing my emergency lights on. After pulling the car on to the shoulder, I have put the car on to parking gear for few minutes and then again shifted back to drive. From thereon I did not face any acceleration problem again for the rest of my 2. 5 hours journey. For safety, I just stayed on right lane and drove with constant speed of about 65 mph through out my journey. It was really frightening experience when I was driving at 65 mph and suddenly accelerator not working and going berserk and car slowing down on interstate. I would like to know what could be the problem with my car and if there are any solutions for this. Please let me know, I am really worried now to drive my car on highways and to go on long drives.
