How to get my Ford Bronco running again.

I have a 1992 full size ford bronco 4x4 with a 5.8 windsor.(Automatic) wit approximtly 30,000 miles on a new engine I had put in it about 4 years ago. Prior to it dying on me it had a severe loss of power just didnt wanna go up step hills n stuff like that. One day I went to go to work n it wouldnt start it was crankin but not turning over. I had a distributer cap, and a new fuel pump put in it. Still no luck. I look to see it I was gettin spark but I wasnt so I took the ignition coil to get tested to see if that was bad but the guy told me it fell between the numbers as being good. Please help me I love my rare four door bronco n I really want in running n out on the streets again
