1999 Dodge Intrepid

After I drive 4 a while, my car gives a little jerk and acts like its going 2 stall. But, it doesnt. My engine lite comes on, but the car drives fine. If I let it set a while the lite goes off or I can take it some where and reset the computer. I beleive it started when I hit a bump and my cruise control would shut down. I would have 2 turn the car 2 get the cruse control 2 work. I dont use my cruise at all but the other problem is still there. What do u think the problem is, could u please help. I dont make alot and i`m short of cash most of the time.
