Help is on the way.

Don't want to sound like a smart alec, but do you have fuel in the tank?
You need at least 1/2 tank, both front and rear, reason is this, Foot valve in tank will eventually fail, leaving the last 3 inches or so of fuel out of reach. Also , selector valve may get stuck, so you might have air coming in from an empty tank.
After fuel level has been established, air must be manually bled from the fuel filter and the injection pump.
Then, open the injector lines a few turns,(till the nut is a bit loose),at the injector.
Crank engine to remove air from lines.
Tighten lines.
You may want a battery charger hooked up while you do this, as a long cranking session will drain batteries. These engines need a bit of speed while cranking,low batteries will compound any previous problems.
I don't check in here that often, but others are around, I'm sure enough talent and experience exist here to help you with this.
Enjoy, Ed.

JUST SHOOTING IN THE DARK BUT IF IT RAN FOR 20 MILES AND QUIT, HAVE YOU CHECKED THE LIFT PUMP DRIVE? IM NOT A BIG IDI MECHANIC SO I DON'T RECALL HOW THEY OPERATE... JUST A THOUGHT
When I got my IDI, one of the first things I did was install an electric lift pump (Facet/Duralift 40285) and eliminate the mechanical pump. I made a careless mistake and hooked the relay to the fast idle solenoid instead of the fuel shutoff solenoid. So whenever the truck warmed up enough to come off fast idle, the pump would turn off!

The strange thing is that it never stopped running. There was just a mild bog when accelerating uphill. Anyway I would check the lift pump, but not necessarily first. I am not sure if mechanical pumps can be "sucked-through" but the electric sure can and the truck will start and run ;)

I have an e-pump as well. I didn't install a relay, but rather an on-off switch that I turn on whenever I start up the engine. One day I forgot to turn on the switch and the van drove fine for several miles. I think as long as you don't have any air in the system or major load on the engine, the IP will suck thru the e-pump just fine. (for short occurrences or emergencies, of course)

Anything over 3 inch diameter exhaust is a waste of money.

Walker BTM is a good muffler. Look for a full flow muffler.
