1996 Chevrolet S10 engine problems

While driving, I notice white smoke in my rear view mirror. Checked all my gauges, which were all fine, and the vehicle was running like normal. I pulled over to the side of the road, and when I got the vehicle stopped, black smoke started entering the driver's compartment. I turned the vehicle off and got out. I opened the hood to find that my engine was on fire. As of this time, I do not know what caused it.

For years my chevy s-10 1996 2wd truck would suddenly shut off on the road often at highway speeds. Chevy looked at the truck many times and always said they couldn't duplicate the problem. One time they talked me into a brand new transmission at 36100 miles. They didn't honor the warranty even though they said that the transmission was the shutoff problem and happened before the 36k warranty limit. That cost me nearly 4000 dollars. They truck continued to shut itself off while driving for years.
