Runs Rough on 2000 Mercury Villager

My village started running rough and stalling out. My brother replaced the fuel pump and distributor. It still runs rough and acts like it will stall out. It doesn't want to go any faster then 25 - 35 mph. The check engine light is on.

The check engine light means that there is a problem with the emission control system--could be sensors, or another component. http://repairpal.com/check-engine-light

Don't replace any more parts at home. You will want to take the car to a good diagnostic technician who can get to the root cause of that check engine light and fix the problem. Swapping parts will eventually cost a lot more and you'll get frustrated without ever getting a fix.
