2003 Jeep Liberty Automatic 87000 miles

i have taken my liberty to the mechanics two or three times for this problem. First the fuel pump was replaced. Then the spark plugs and sensors were replaced. The car is still doing the same jerking motion every few days and at times stops running all together. The mechanic cannot find anything else wrong with it. Any suggestions? -Thanks
