Check your earths - could be one of them is dirty but is only breaking down under load.

The earths - from the ECU to the chassis, from the engine to the chassis and the engine and battery to the battery.  A dodgy connection to any of those, which is cutting power could result in no sparks from time to time and backfiring.
