On my whirlpool gold gas oven, I've had problems getting ignition and consistency in temp. I've replaced temp probe and the oven burner / igniter. Now it ignites consistently when first started. The burner runs for a bit then cycles off. However, if it needs to come on a second or third time it has Tribble igniting. You can hear the ignition going but no flame. I think the spark unit is fine. The broiler and cook top all work flawlessly. I'm out of ideas.
