general problems of the 2004 Dodge Caravan

I was traveling on the freeway at speed or slightly above when my gas light went on and the van started to sputter. Then the engine light went on and my speed decreased to appx 40 mph. I immediately got to the side of the road during rush hour and cars speeding by me. It was extremely dangerous and scary. A police officer stopped to assist me and try to get me towed. I made it to the next gas station. I added gas and oil. However, due to the fact that it was shaking and not able to make it above 40 mph, I decided to have it towed home until a decision could be made about what to do. The next morning we towed to our mechanic and it was discovered that the engine dropped. The bolts that held it in failed. I am lucky. Now we have the engine back up in place and are determining what else is broken due to this failure.
