At times, car will not accelerate.

It has lasted from a few seconds to 10 minutes. It only happens periodically, and no trouble lights appear on the dashboard.
The vehicle had a hesitation upon acceleration between 40 and 60 mph. Also noise was coming from the engine. Especially on a cold start. Brakes were pulsating.
Car looses power while trying to accelerate. Have almost been rear ended on a couple of occasions. Once while on I-95 in georgia, a semi-truck almost rear ended the vehicle.
