Hey Scotty
I have a 1988 f150 that dies when warmed up so what I’ve done so far and no change : new rear tank and fuel pump low pressure pump and in-line high pressure pump , fuel filter , map sensor , fuel pump reservoir nad now thinking on moving to the ignition control module I just have had a hell of a time tracking this problem down
You don't seem to have narrowed this down to either a NO SPARK or a NO FUEL issue yet.
You should do that.
Here's how.

So when it dies, check if the coil is producing spark.
If the coil is sparking, spray some starting fluid into the throttle body and see if it tries to start.
Once you figure out if you're chasing down a spark or a fuel issue, it shouldn't be hard to nail this down
