There are several reasons why your plugs will "foul". Piston rings leaking oil into combustion chamber, carbon build-up in cylinder, low voltage causing improper firing of cylinder, so on and so forth. The simplest thing to do is make sure your ignition system is working properly and start troubleshooting from there. Did you put new plug wires on and then the problem started? If so, you have the firing order wrong.

As I remember it is a 1990 F150 with a 5.0 V-8.
MY recommendation to you is to STOP throwing money at the little pick-up, and begin REAL diagnosis, or take it to a repair facility. It may be expensive, but less costly in the long run.
There are many causes for your plugs to foul. You have addressed some of them, but here are some others.
1) Kinked or pinched or otherwise restricted fuel return line.
2) Dribbling injectors, or WRONG injectors (has the engine been modified or otherwise "repaired")
3) Damaged, defective or incorrect Coolant Temperature Sensor (the sensor for the PCM, not for the instrument panel).
4) Incorrect, defective or missing thermostat (the PCM expects to "see" temperature around 190° to 220° F.
5) A defective MAP sensor or vacuum feed line.
6) Oxygen sensor shorted to B+ at the signal return.
Have you checked the PCM for codes?
You can go here----->

...and scroll down below the code descriptions to read the procedure.
NOTE------> You DON'T need the meter. Make the jumper connection as detailed in the procedure, then sit in the seat with a note pad and turn the key to "Run" but do not start it. Pay very close attention th the "Check Engine" light. It will "flash" the codes to you. Pay attention. Don't Space Off here. If you get distracted, or if you want to be REALLY sure, turn the key off for > 30 seconds, and start over.
"***, pause,****, pause, **, longer pause indicates a "342" code.
With this information, use a repair manual for proper DIAGNOSIS and subsequent repair of the SYSTEM or CIRCUIT indicated. Don't ASSUME that the code for a fault in the MAP circuit is a defective MAP sensor. It MAY be, but it could also be a disconnected or broken vacuum line for the sensor as well. Diagnose the circuit or system as a whole.
Good Luck

Does the car blow a lot of smoke? If it black, it is getting too much fuel. If it is white, it burning oil.
Curing the fuel problem will be a lot simpler than curing the burning oil. Since you don't identify your make and model, it is hard to say what measures would be appropriate to repair the problems.

Did you set the gap on the new plugs? Incorrect gap can cause plugs to burn the electrode off,quickly.
