Q: Decreased Consistent Acceleration on freeway

asked by on

I bought my '94 Mercury Topaz V4 Automatic about a month ago. I pulled the codes and it had a P158 for the MAF sensor. I replaced the MAF sensor, air filter, PCV​, and fuel filter. I was on the freeway today and I noticed it was making this exaggerated revving sound after 60 mph. Then it slowly and consistently lost speed. I immediately got off the freeway in time to coast into the gas station as it cut off. Then when I tried to restart it, it won't turn over. Help!

My car has 466339 miles.
My car has an automatic transmission.
