1996 Chevy Beretta Fuel Filter OR Sensor?

Engine Mechanical problem
1996 Chevy Beretta 6 cyl Front Wheel Drive Automatic 160k+ miles

I start my 96 beretta, it runs for about a good 3-5 minutes and it starts to stall and then eventually dies. Ive been running Fuel cleaner through it since I bought it. This car is a beast and has never had any problems till recently. But it does start. When I first Noticed the problem it was when I was driving, it sounded like it wanted to shut off and it wouldnt accelerate while I was driving. It was almost like I was out of gas. A friend told me it might be the fuel filter or a map sensor or someting like that. Ill answer any questions if you need to know more info. I love this car I dont know why but id like to keep it going. Help me?
