I have had a couple of strange things happen with my Stihls. If I put the saws in the back of my p/u, and drive a few miles and stop and try to start the saws up quick, they wont. They seem to flood out, change the plugs, still won't start. I let the saw sit for a hour and they start right up. This happened 3 times now with 2 different saws. Other than these problems, they run beautiful. Has anyone got any ideas.

Vapor lock. Try to keep them out of the direct sun so the fuel doesn't cook, and crack open the gas cap and then close it again before you try starting the saw. That will relieve the built up pressure.

Suppose you fill a bottle with water,cap it with a stopper with a tiny hole and hold it upside down.
What happen? Nothing.No water comes out.
But suppose you shake the bottle while its upside down? You will get water falling out.

Well, that's exactly what is happening in the case of your saws.The fuel is getting forced into the carb barrel from the metering chamber due to the shakes (however gentle) while they are in your pickup.

Nothing else to do except move the switch to 'Start' (fast idle) when you start them up after the 'joyride'.

Hope you have held on to those old plugs. There was nothing wrong with them.
