400 V8, if it matters. Was sitting at idle, running beautifully as usual, and it gave a quick sputter (maybe 2 seconds) and died. Cranks and sputters, won't start. Entire engine is new inside and out, even the carb and distributor are new. However, I reused the coil (cheapskate lol), and did not replace the electronic ignition module. I'm thinking that the module is the most likely culprit, since it is original. A module is $30 from Rock Auto, and a coil is $10. I figured I'd replace them both like I should have anyway, but what say ye about what's the most likely cause? I thought module, coil, fuel pump, in that order. It's definitely not out of fuel. I even tried switching from the front tank to the rear tank, would still not start.

I'd lean towards spark being the problem and especially suspicious of the module.

Module is original. No idea why I didn’t change it when the engine went in. 😬 There was no need, it took decades to beat the idea into my head, if it ain't broke don't fix it. Except for water pumps that have been off and dried out, those get scrapped. I put too many back that leaked shortly afterwards. I'd rather have an OEM fomoco module than a chineseum one.

Of course any complaint of crank-no-start should begin with a fuel/spark diagnostic branch: Is there a strong, intact squirt of fuel generated from the accelerator pump when the throttle is cycled? What does the spark look like when asked to jump a gap between the coil wire and an engine ground? The next list is highly UNscientific, and merely percentage bets, accumulated from spending a few years in an automotive electric shop in the early 80's. The most-failed component in early electronic ignition systems: GM/HEI - cap and/or rotor Mopar - ballast resister Ford - control box 
Down to just a blue car now.

IIRC, the spark box was a finned aluminum deal; they could be trouble-prone.
I recall replacing one ago on a buddy's '79 Ford Ranchero.
Same symptoms, and I don't recall anything visual like leaked potting material.
"EEC-IV" (IV as in 4) comes to mind...
A LOT of water's passed under the bridge since then, so I could be off on the Gen 4 nomenclature. Best way to identify the aluminum box type modules is by the color of the plastic where the wires go into the box. Don't let anyone try to sell you a box that has a different color cause it won't have the same plug ins.

Coils and fuel pumps tend to cause symptoms long before outright failure. Modules are like light bulbs, they work until they don't.

It’s not Chinese. It’s the original box. One that has lasted 30+ years and commenters are complaining that they are unreliable, lol. Since you did zero troubleshooting no one is able to offer a cogent response other than to say the abrupt shutdown points to something in the ignition circuit, it could even be a fuse.

You don't read so well do ya? We're telling him not to buy cheap crappy import replacement parts. We didn't say the original was garbage.

I will quote for your edification. IIRC, the spark box was a finned aluminum deal; they could be trouble-prone.

Yeah, big difference between likely failure and all junk.
That said, avoiding a no name replacement is the best bet.

Hi , As stated above , the color of the Wire Grommet on your ORIGINAL Ignition Module Box should have been Blue . Fold had multiple Grommet Colors for Different engines + Setups . NO idea what color Your Chinese Box Grommet Color is . The 1 in My 1984 Died on me at a Gas station . Truck Running Perfect , Pulled in to get gas , Shut off my Truck . Go to Restart , Nothing . Crank , Crank , Crank . I said Great , just like My MOPARS with the Ballasts . 
Get a Ford Box , NO Chinesium . Ronnie
