The switch is being subjected to too much current draw or the connectors are burnt and are causing a high impedance joint

Both produce heat , both will kill switches

Check the rating of the replacement switches it will tell you what they are able to take in the way of load and fit new spade terminals or make sure that the connections are clean and bright.

Have you fitted any other items to the mower such as lights with halogen bulbs

If so then you will have to put a relay into the circuit and use the original line as a trigger for the relay

This we call hunting, it is due to a fuel blockage in the carb, it needs the carb and jets cleaning, if you are ok on the spanners, remove the carb from the engine, remove the screw in the float bowl and remove the bowel, the main jet and emulsion tube are screwed up inside the carb, remove and clean, you can purchase jet cleaning wires which will sort out the cleaning, you can also use carb cleaner.

I would guess you would hear and feel excessive vibration when the blades are engaged, other wise you will need to remove the deck, or put the machine up on some car ramps, once you can get under the deck see if there is any sideways movement on the blades.
