While driving car slips to lower speed and it won't allow me to excel even when my foot is on the gas

What is your question?

First, my battery died. Once I jumped it and got it going again, my car was running fine for about 20 minutes. Then all the sudden when I was going about 30, my car slowed down on its own (no matter how hard I pushed the gas peddle) and it would not excel past like 5 miles per hour. Almost all my lights on my dash started to come on. It sounded and felt like it was trying to "kick" back into gear but couldn't. It finally slowed down until it stopped. However previously, I could be going 50 miles per hour and it would slow down BY ITSELF to a lower speed and wouldn't excel even if I pushed the gas peddle. It didn't quit because it would eventually "kick" back into gear.

How long has your 2009 Kia Sorento had this problem?

Couple months..It had gotten better then got worse again
