Assuming it is electric start it sounds like the spark source is having troubles reaching the flammable fuel/air mixture.
It could have burned the tip back a bit (think worn spark plug electrode), or it has been knocked out of alignment. this will allow the volume of fuel/air mixture to accumulate to a greater level than normal. When it finally finds the 'spark' there is a larger ignition than normal and hence the popping.
It has a pilot. Everything looked ok when I took it apart and cleaned it. Maybe an obstruction in the burner keeping the gas from reaching the pilot. I was just hoping someone had the same stove and similar problem. I researched blogs and such with no results. Bill
my heating stove was doing the same thing last year, cleaned everything as said above. But that did not fix it. Ended up puting a new gas valve on it that fixed the problem. According to the company that made the stove condensation causes rust in valve which slow down gas flow.
Had a similar issue with furnace. Cleaned, new thermocouple, etc, turned out to be gas valve. Would hang up and then slam,open,releasing a big volume of,gas instead of a regulated volume. Would get an explosion of the gas instead of burning. would be Ok until it shut down and cooled,down and then tried to,reignite. New gas valve fixed it.
Good luck, nice stove, I had the woodburner type until I got too old to,deal,with wood issues and chimney cleaning . Have a propane now and although more,expensive, it is a lot easier and cleaner.also,zero,clearance so,you don't get burned.
