Stator Assembly
The stator's source coils often develop internal insulation breakdown that manifests only under thermal load. When the engine reaches operating temperature, the heat causes the copper windings to expand, breaking electrical continuity and stopping the spark. Cooling the sled for a short period allows the metal to contract and restore the circuit temporarily.

Ignition Coil
Similar to the stator, the secondary windings within the ignition coil can fail when heat-soaked. The increased resistance from thermal expansion prevents the coil from stepping up voltage sufficiently to jump the spark plug gap under compression, leading to a stall that resolves once the coil temperature drops.

Exhaust Temperature Sensor
A biased exhaust gas temperature (EGT) sensor can send an out-of-range high-temperature signal to the ECU once the pipe is hot. While this often triggers a 'Limp Mode' (ECU 17), certain failure states or harness shorts can cause the ECU to terminate the ignition sequence to prevent perceived engine meltdown.
