This occurred to me yesterday while traveling 60 mph in 94� f heat on I-76 e just before the 676 / 76 split. I was traveling in the far left lane when the car suddenly lost power. Looking at the dash I noticed the shifter had moved itself into n (neutral), it would not move back into drive. I applied my hazard lights and began forced my way rightward across three lanes to the shoulder, speed rapidly decreasing and seemingly more sluggishly than a normal coast. I think the emergency brake was automatically being applied or I was fighting a braking system. One lane from the shoulder, a ups truck was headed for me from behind. Luckily, he was able to swerve into the shoulder and pass me there as he could not move left into other traffic. We only narrowly avoided a collision with me or the elevated barrier on the side of the road. I had only 10 mph left and no ability to redirect my vehicle. Once on the side of the expressway, I was able to google this well-known issue with the vehicle. I let the vehicle cool off, turned off the air conditioning, though didn't want to risk turning the vehicle off. I was concerned I would have to wait until nightfall to get back into traffic (still flowing around 60 mph and a very narrow shoulder) luckily during a small traffic backup up the road I was able to re-enter traffic at a modest speed. I crossed my fingers as the rest of my commute (another 2 miles or so) was 95% highway driving. Luckily the car held out for me to get home.

My 2004 Prius's check engine light turns on randomly wnd often and I lose full power of the car. The battery is fully charged. The car stopped 4 times today - lost all power and the brake would not stop the car.
1) after breaking gently to a stop, the car switched to battery-mode and reported errors, including "check engine" 2) the car would not switch back to the gasoline engine, and could only be driven at 40mph on battery to the dealer 3) the dealer reported that the error codes suggested the onboard computer had to be reset, and once it was reset the car went back to normal operation.

Dealer said had trouble code in computer and have corrected problem but let them know if happens again or any other problem. Engine load, automatic gear shifts hard and car rolls slightly when put into park.
