I typically attribute a sharp stall and restart to an electrical problem. Sputtering and stalling is usually more of a sign of a fuel problem.
Did you have the clutch disengaged when it restarted or was the trucks momentum acting as a starter? | | |

A sudden and total loss of power (engine run) followed by later restart can, on rare occasion, be the result of fuel starvation. But, that is usually more intermittent and residual fuel will usually allow some irregular running or sputtering.
I don't know nuthin' about fancy electronic ignition systems, so you are out of my league there.

Those wires have a nasty habit of breaking the conductors inside the insulation, and interrupting the circuit under the proper vacuum and load conditions. The stock HEI ignition was notorious for flex wire problems with the pickup coil, and it's possible your aftermarket ignition system has something similar.
