Not much info but sounds like it could be vapor lock. Check to make sure that your fuel lines are isolated from the engine and wrap with insulation, if necessary, to keep the lines cooler.

SOURCE: 1987 ford bronco fuel issues

First thing to check out will be the fuel pump relay under the hood. It is the one who drives the pump, so if it is defective the pump will not work either to prime the engine, or to make it run. Secondly, you need to check if the fuel filters are OK cause sometimes they clog up and prevent enough fuel from reaching the engine. Thirdly, check the injector(s) for cloging, and clean or replace them as needed. If none of this helps, then the problem probably has nothing to do with fuel delivery, and the next step to check will be the whole ignition system, which is also one of the most comon bronco problems.

I had the same issue on my '86 Bronco. Change the ECM(computer) and your problem will go away.

SOURCE: 1987 FORD FULL SIZE BRONCO FUEL PROBLEM, SHUTS DOWN

The only way air can get in the fuel line is if you have a hole in it! Problem of course is were? I would run the fuel line from back to front and back again. Look for any wet spot that you can find. You may even have to drop the tank to ba able to look on top. I would suspect the problem is in the line before the high preasure pump, being as you are pulling air into the system. I have seen leaky lines allow air in, but not let fuel out.

1987 f 150 6 cyl starts and runs till hot then wont till cooled off


Probably a bad ignition coil or a bad TFI module (the ignition control module). Much testing could be done to find the faulty part, but I believe if you take the TFI module to a parts store, it could be tested.

302 bronco stalls after it warms up and won't start till it cools down


I am guessing its your TFI or Thick Film Ignition module. Usually located on the underside of your distributor, its either grey or black in color and often when it is going bad it acts like this: Usually starts fine, runs ok for about 20 min then engine dies. cranking engine sounds normal but no start. checking spark will have no sparks. Leave hood up and allow to cool (also TFI very hot to the touch) I packed Ice around it once (in a ziplock) that made it run in about 45 min. NOTE: get ready to replace real soon because its on the way to breaking down.
