Clicking range igniters

I have a 6 burner American Range. When I turn on the oven it begins to heat up without problems, then after around 5 minutes, the igniters for the stove top burner all start to click and continue for around 5 minutes, then they stop clicking. The oven is working fine and has heated up. There will be random clicking of the ignitors from time to time.

Any ideas what the problem might be?
