Why does car shake after the car reaches 65 mph but can pull over and it drives

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. It is difficult for me to know from your description if your concern is engine performance related or suspension and steering related. Based on my interpretation - which could be incorrect -- it would seem that the engine does not perform properly at 65 miles per hour, but when restarting it starts working fine. Sounds like some hands on testing by a technician near you is the best first step to resolving your concern.
