Another possibility is a blown alternator, this is the device that turns your engines power into electricity, and charges your battery. Car cannot run without.
It is important to maintain speed while driving, unless coming to a stop. A car would decelerate if there was not enough fuel or electricity to keep the car running.
There are 2 fans that would be running while you are driving and that is normal... the compressor fan if you have the air conditioner running and the radiator fan runs to help keep the radiator cool while the engine is on.

faulty ignition switch
Fuel pump failure is one possibility.

Some things that can cause a car to stall while driving it include a bad fuel pump, running out of gas, and low fuel pressure. A clogged catalytic converter can also cause this to happen.
Possibly, you have a broken timing belt.
