Issues with eddie
So I'm trying to figure out what is wrong with my bronco. To start with it's a 94 bronco eddie bauer edition with the 302 an e40d with 230000 some odd miles stock. When I start it up it starts just fine put it in gear and go but after it warms up ,it seems like, you put your foot to the floor it revs up bogs down back fires through the air intake so I hear a popping banging what have you from under the hood and seems like it's coming out of gear or just losing that much power that im not moving and eventually roll to a stop I then shut it down turn it back on it runs fine for about 30-45 seconds then does it again. With a fresh start though if I only use half throttle it seems to have all the power in the world and goes longer before it acts up again. Now this doesn't happen every time sometimes it runs with no problems at all. So was wondering if anyone can help diagnose the issue because I feel like I'm about to be replacing sensor after sensor.

The Ford engine control system for these vehicles runs in two modes: in open loop, used when the engine is cold or at wide open throttle, the Powertrain Control Module, or PCM, uses preprogrammed default values; in closed loop, used once the engine has warmed up, the PCM calculates values for amount of fuel and spark timing and EGR amount and idle RPM based on the inputs from several different sensors. And yes, sometimes those sensors fail or something else causes them to deliver bad data -- and GIGO applies.
GIGO? Yep; Garbage In, Garbage Out.
Fortunately, the PCM can also store data about which sensor is feeding it garbage data. All you have to do is ask it nicely and it'll tell you. Instructions for asking it are available at Fuel Injection Technical Library » How To Run a Self-Test or you can get the Equus 3145 and use it. Lots of folks get them from Amazon.
Me? When I needed a code reader now my local Advanced Auto had an Actron on the shelf. It blinks a light and beeps, while the Equus actually displays the numeric code. I know which one I would get if both were available at the same price -- the Equus.

Sounds like a fuel delivery problem.
You either have a clogged fuel filter or a fuel pump getting ready to quit.
You need to put a fuel pressure gauge on it and put the gauge where you can see it and have it do it. I bet it drops to below 30psi when this happens.

It's a 3/8" fuel line tool. Lisle makes it, as do others. It clips over the fuel line then the tapered end pushes into the fitting on the fuel line to release a garter spring inside and allow the fuel line to come off the fuel filter.
The tools look like this. (This is the complete set. The little picture at the bottom shows how the tool is used to remove the line from the fitting.)
A little penetrating oil will help get the fitting to release when you're removing the fuel filter. To install, no tool is necessary; it just slides back together.
