Check for spark.
Check for fuel (clogged filter?).
... what was outdoor temp when the engine stalled? Vapor lock problem?

OK, I'm lost. If you're getting spark, why are you replacing ignition components? What am I missing here?

Sound like there might be a problem in that system? Since you have done the throw parts at it troubleshooting attempt on the rest. lol
I have seen the propane system one time on a truck and it looks like a PITA.

Air, fuel (propane) & fire (spark)... one of the three, right?
Sorry I do not have any propane powered experience.
Does it have a propane pressure regulator? Or any thing that controls that part of the system that you might of missed?

Where is your coil mounted? On a 78 Fairmont I have, I had the coil mounted on the intake right next to the carb. It would shut off right at 15 minutes every time just like it ran out of gas. I moved the coil to the driver side fenderwell and it has seemed to solve the problem. I have been told older Fords are prone to do this.
