that would be a Speed Density System. It runs by way of Manifold Absolute Pressure. measuring the air into the manifold and heads instead of the initial air charge and exiting exhaust temps.

What is the TFI Module and what exactly does it do? Yes the truck will run fine until it starts to warm up. then it does the sputtering and dying out. it hasnt done it to me on the interstate yet but around town and especially coming up to lights it has been doing it.
It is called the Thick Film Ignition module...provides some spark...my 88 F150 did it too...a real pain in the neck to diagnose at first as when it cooled down it was all good. I got used to waiting for 30 minutes on a hot day every once in a while!
Good luck.
