why does my car rattle after driving it for a while?

[megustanatasha]

i drive a 95 civic. in the morning when the car is cold i drive and everything is fine but then after a while driving around from place to place the car hesitates and rattles when i get off 1st gear. today it was giving me this problem after doing some errands. i went home and the car cooled down for like 4 hours. then i jumped in the car and drove around and it was fine until after a while it kept shaking on me. the car doesn't want to shut off but just give me a good shake. i dont know if its my driving but i have been driving stick for almost a year and i had no problem like this with my other car
