It sounds like it having a delay of lighting the gas when the main valve opens.. This is something I would call a Pro in on.. Gas is NOT something to mess with or put off on..

Like Jay said get a tech in to look at it now. The delayed light up could be from dirt , lint ,spiders in the burners and lighter strip there are other things also so call a tech to look at it .
