Can't figure out the stalls, fuel starving, whatever it's is

yo Bob,
WELCOME!
Try a Self Test for Diagnostic Trouble Codes (DTC)s
http://www.therangerstation.com/tech_library/OBD_I.shtml
A helper is good to assist in reading Codes; best is to take a cell fone vid and replay it.
Some basics;
Visual Check
Battery is fully charged & connectors and grounds are clean
Inspect the air cleaner and inlet ducting.
Check all engine AND HVAC (under hood & in /under dash) Vacuum hoses for damage, leaks, cracks, blockage, proper routing, etc.
Check headlights
Check EEC system wiring harness for proper connections, bent or broken pins, corrosion, loose wires, proper routing, etc.

89 Bronco 2 V6 2.9 Spesc @ http://www.broncoii.org/techpages/2.9specpage/index.html
Fuel Pressure Key On Engine Off 35 - 45 psi
Fuel Pressure Key On Engine Running 30 - 40 psi
Pump Test;
"...Here is the step by step test you can go with a 12 volt test light or a DVOM (volt meter)
Access the Tan/Light Green (T/LG) wire at the self-test connector. Jumper this circuit to ground with a jumper wire, when the ignition switch is in the Run position, and listen for the fuel pump relay to "click".
At the fuel pump relay, check for the Red (RD) wire to illuminate a standard 12-volt test light with the ignition switch in the Run position. This circuit is a battery voltage feed from the Electronic Engine Control (EEC) power relay and is the same circuit that provides power to the fuel injectors and the Powertrain Control Module (PCM).
Check for the Yellow (Y) wire to illuminate the test light as well. This circuit is supplied power from a 20 gauge fusible link at the start solenoid and should be hot at all times.
The Orange/Light Blue (O/LB) wire is the circuit that provides power to the fuel pump when the relay is activated by the PCM's grounding of the T/LG wire. Installing a jumper wire between the Y wire and the O/LB wire should result in the fuel pumps running and fuel pressure at the injector rail if the circuits and fuel pump are in good working order.
If grounding the T/LG wire at the diagnostic connector results in the fuel pump running and the truck starting, it indicates a failure of the PCM driver that controls the pump relay or a circuit issue between the PCM and the diagnostic connector on the T/LG wire.

TFI Module:
Your Ranger/Bronco II is stalling/dieing or sputtering when hot but runs when it cools off. This can be caused by a faulty TFI and the biggest culprits are heat. Another culprit can be a wire grounding out. Problematic TFI's can give off codes 14 (PIP) and 18 (SPOUT).
