Ditto the above but another idea: How old is the mower? If it's newer and has the automatic choke I've read about some owners having a hard time restarting after a brief shut down due to the thermostatic element (usually attached near or on the muffler) cooling faster than the engine, being the muffler is sheet metal I guess, so what happens the choke kicks in but the engine is still too warm for such a rich mixture. The thermostat should have a link wire running to the choke arm on the carb if yours has this.
if it's an older L head or flathead Briggs with the suction feed carb (carb mounted to tank) these can be notorious for hard restarts, years ago a neighbor had one on a B&S 3.5 hp and it wouldn't restart after emptying the bag, so he just took a drink break and 20 min to 1/2 hr later it started on one pull, I've also had that with an old L head of mine.
Good luck, hope we can help here, this a knowledgeable group.
