intermittent gas oven operation

Gas bake oven seems to have a mind of it’s own I had read in the forum about a modified(updated-8 lighting holes instead of 4)on some Whirlpool ranges do I need this for my oven possibly in addition to a new igniter.It seems that the more I use the oven the less the problem occurs…also when I had lit the broiler for the 1st time it seemed to cutout and work fine after re-lighting. FYI we had just moved into this home so I don’t have a track record on the appliances.
