This demonstration guide answers one field question about a module that sparks cold and dies hot. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with hot-spark after a documented run. That reading separates a module that sparks cold and dies hot from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the ignition module as the primary path. If it is in spec, do not replace the ignition module just to complete a parts list.
Repair the failed system
The usual correction is the ignition module, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about a module that sparks cold and dies hot.
Stop before you make it worse
Do not packing the module in grease to "keep it cool". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the ignition module is corrected, convert the visit to a broader diagnosis rather than stacking parts.
