Three things come to mind:
1) The cooling fins that keep the engine cool are blocked by debris and letting the mower run hot.
2) The coil is getting hot and breaking down causing it to not get spark to the engine.
3) There might be an exhaus leak near the carb causing the gas to vapor lock.

Why does a Briggs and Stratton lawn mower throw oil in the exhaust and carburetor?
The intake valve is not closed deep enough into the valve seat due to being too long and crankcase pressure is allowing some oil from the engine to be sucked up the valve guide into the combustion area and the 4 cycle process allows some of the oil to be pushed into the intake cycle and thus gets into the carburetor intake area and then into the exhaust system as the engine completes the cycle. Can also be caused by the mower turning over or when the engine oil level too high.
Is there a gas filter on a Briggs and Stratton 4.5 HP lawn mower?
Usually these smaller engine dont use fuel filters. If there is one though it will be located on the hose that goes from under the gas tank before it gets to the carb. They come in various version. Usually they look like a disk looking thing with a hose going into it and another hose going from it to the carb. Just remove the hose clamps and replce it or blow it out. It depends on the type it is. Good luck.
