1993 Jeep Laredo Starts, Shakes, then Dies

Hi Car Pros,

My 93 Grand Cherokee has a lot of miles on it but I have not had to repair to much since I've owned it. This is what happened to me today;

I started my car and everything was like normal, about 15-20 seconds later the car began to shake then more violently until it died.

Please tell me what is wrong with my Old Jeep.

Thanks Car Pros
