Mike1, that post is 5 years old.  Check the engine grounds in front of the starter, and also, unplug the Duetch connector at the injection pump, and inspect for loose pins and cracked wires...  You could, wiggle that plug while it's running to see if it cuts out and in, before you unplug it.. it should be secured in a yoke

Did you ever figure out what was causing the truck shutting off . I have a1994 ch 613 em7 300 vmack 1 with very similar problems

I am looking for a fic module for a 1994 Mack ch 613 it has ‘em 7 300 vmac1 engine the part number is 12 ms 45 m4 I am still having random shut downs while idling and driving, I have rebuilt injection pump and repinned Deutsch plug on both ends . When I tap on FIC module, I can occasionally get the truck to shut off.

If anybody has any other ideas, let me know

I have 1994 Mack em7 300 V Mack 1 randomly shuts off at idle  and when driving I had injection pump rebuilt is it possible to have a bad alternator or regulator that is supplying erratic voltage to injection pump
