why is my car coasting whileI am driving?

I have a 93 Pontiac Bonneville. I have had this problem before where I would be driving, then all of a sudden, when I am pressing the gas, it would slow up and then the when trying to press on the brakes, they are hard and I can't press down then the car cuts off. A few minutes later, the car started up with no problems. Any ideas on what could make the car do this? Serious replies only and thanks!

Also, my car would be shuddering/shaking when I would be at a complete stop.

The reason the cars slows when you give it gas is the same reason the brakes are hard- it has already died out, you just didn't know it yet. You probably need a tune-up or a gas filter.

It seems like a sensor to me.
