1996 Dodge Stratus died and wont start

I have a 1996 Dodge stratus 2.4 ltr. The tachometer quick a few weeks ago. Then I was driving today and going up a small incline. I tried to accelerate, but only made up to about10-15 mph. Almost at the top of the hill it slowed and died. It did not sputter and seemed fine before I started up very small incline. I was low on gas and added some thinking I had just ran out. It will turn over, but will not start. Checked fuses and added more gas. Nothing. We had the fuel filter changed less than 6 months ago. Have had a lot of black deposits on pipe of muffler. Have about 93,000 miles and have had egr replaced 20000 miles ago along with cataletic converter. Please help. Thanks Donetta
