Problem came back all the sudden

[conoco]

About 2 months ago I posted about how I didn't have and spark. That post tons of people chimed in and I ended up getting my truck to start back up. During that time I have taken my truck on 2 fishing trips and about 900 miles total. My truck has ran flawless. Starts first turn, when it sit over night out side she fires right up.Power is great and most that driving has been at highway speeds. I was just driving to an appt hit the highway for about 15miles and all the sudden truck started to sputter and then die. I gave it a couple minutes and it started right back up. Drove about a quarter mile and it did it again. Now it Wil not start at all and I have no spark. Anyone have a clue or anything I can trouble shoot? I am beyond frustrated. Thanks for any help again.
What I replaced after my first post
New distributor with coil
Spark plug wires
Spark plugs
Ignition switch

What I have done so far
-Test light shows power to the batter wire of the coil with the key in the run position
-put a jumper cable on the positive battery post to the batt wire on the coil and nothing happens
-tested fuel pump and it is 5.5psi and good.
Fuel filter is clean and gas shoots in the carb when I engage the throttle.
