My car decelerated rapidly on highway shut off and now won't start.

What is your question?

I was driving down the highway at 70 mph and the car was running great with no issues at all then all the sudden the car started slowing down really fast. I tried to give it more gas and even went as far as flooring it but it still didn't help. The engine accelerated but the car stislowing down was drastic enough that it felt like someone was hitting the brakes and I could hear the engine trying to accelerate but it still continued to slow down the same. I pulled over to shoulder while I was going about 40 mph and I put it in neutral to see if it would start coasting and the car shut off. When I stopped I saw a little smoke from under the hood so when I looked there was a very noticeable amount of oil puddled on the top of the transmission. I checked oil and transmission fluid levels and both are fine but now the car turns over but won't start. I checked the antifreeze and it was completely empty. I filled it but the car still won't start but it tries to turn over. Please stil

How long has your 2004 Kia Spectra had this problem?
