I was driving on the freeway at 65mph when it just lost power all of a sudden. I can start it, but it barely runs, extremely rough and shakes hard and when you give it gas it just runs even rougher and power loss untll it dies

Thanks,
i checked for restriction and it sems to be ok. I'll still at a loss because of how it happened so sudden, going from running ok at 70 mph and then just shutdown. No sound or noise, but like something went. I coasted to the side of the road. And like I said, it will turn over and start but idles rough and won't stay running
