Sounds to me like a week coil, to do a quick check when it is dark pull your coil wire off from the cap run a wire from it to some where you can see it and about one eighth of an inch from the body, from the drivers seat and crank it over (or have someone crank it over for you while you look) and if the spark is bright blue its ok. but if it is yellow and not that bright then it needs to be replaced

I have an 87 ford Bronco 2. I just replaced the head gasket. I got it all put together. I have the timing in the right place. I am also getting fuel. I checked the ignition and I'm getting spark. I know...

Although you have the 3 components to make it go ,you will also need the correct firing order. It is possible that the ignition timing is 180 degrees out . Right now you will have spark but at the wrong time on the wrong piston.

Just a guess here, but check your ignition coil. Make sure it's mounted nice and tight to the block. a bad ground on a coil will mess with you bad. other than that, I'd check and replace your fuel filter.

Without seeing it it is a hard thing to diagnose. You could have an injector leaking, possibly a fuel line. Do you smell gas? Sometimes with fords around the fuel filter leaks because of a broken clamp. The o rings around the fuel injectors could be leaking, or one of the rubber fuel lines. If you go off road alot, you could have a pin hole in one of the rubber or metal lines. Check and get back with me and I will do the best I can to help. Hope tis helps.

87 325 runs good when cold then starts dieing idling up and down

I would suggest changing the FUEL PRESSURE REGULATOR mounted on the fuel rail with a vac line going to it.
it could be a number of things, if it dies when its warmed up it is most likely a faulty fuel pump on its way out, but it could be anything, need more info. 
Check the spark plugs, change the fuel filter, when was the last time the timing belt was done? how many miles are on it? 
lastly sometimes these cars have old relays, as found on the e28, they were known for not working when they warmed up, change the fuel pump relay with a new one ($7) just to be safe.

Missing out and dies when warm

reach to the underside of your egr valve and feel to see if the diaphragm moves as it warms up. if not you may need to replace it. be careful not to bur yourself though, the engine and egr can get very hot very quickly

Hard starting after warming up and Driving

sounds like a bad ignition control module..since you said a 2.8; it sounds like a GM product; when they start to get age on them; the heat starts to affect them..sometimes until they cool off a car will act like it has no battery in the car at all. Check to see if the module is the problem; depending where the location of the module is; you could probably do this yourself; but make sure the cables are off the battery before you try anything electrial
