Welcome to FTE and the Big Bronco Forum. We will do our best to get you the most accurate info we can dig up.
Your best bet is to pull fault Codes from the computer (ECA). On a 96 you will need a scanner or need to beg, borrow or steal one. You can sit there and guess and throw money and time at something that MIGHT be the problem but it will be a lot simpler to let the truck itself "tell" you what has it under the weather.

+ 2 on getting a scanner. I also have a 96 and yet to get a scanner, but am going to soon. Having a 96 is nice since you have OBD II so you can get a scanner.
I'm looking at this one as it seems to have good reviews and is fairly cheap:
Amazon.com: Actron CP9550 Pocket Scan Plus CAN Diagnostic Code Reader for OBDII Vehicles: Automotive
A scanner can tell you exactly whats acting up so there is no guessing on what may be wrong. Has your Bronco been doing this for a while or did it just randomly start?
As for your symptoms. There are too many things that could be causing it to give any definite answer, however I'll give some of the little advice that I have. Some of those symptoms could be due to a vacuum leak. The lines are old and easily break if stock so check those. Also, may be possible for something to be wrong with your EGR valve or system but like Greystreak said, its best to get a scanner or go to your local Oreilly's or Autozone (if you can drive there) and they should be able to pull codes for free!
I wouldn't attempt any repairs except for maybe looking at vacuum lines (since that's cheap and easy) until you get the codes pulled!

Take the truck up to any local Parts store, Advance auto, Autozone.... They should have an OBD II scanner and will check the codes for free. Then post them here and we will be able to help you better.

It might be the fuel pump. The fuel pump is in the gas tank so it's a JOB. Have the fuel pressure tested at operating temperature.
Check the timing and the spark plug wires for resistance and continuity.

I'm not sure on the 96's but isn't there a secondary pump along the frame for low pressure that is known for having issues? It shouldn't be too much of a job for an intank one, just make sure as much of the gas is drained as possible to make it easier to drop, then pull it down. Unless you have customized a hole in the bed of yours to access it easier

Nope. Ford went to a single high-pressure in-tank pump in 1990 and it remained so through the end of production. I will reiterate... pull codes before arbitrarily replacing components. Yeah, you might get lucky and get the part that failed but its far more likely that you will spend time and money unnecessarily on parts that MIGHT be the problem and still not actually FIX the problem.
