Hi Janet,
its the warning button on the grass collector. If the button is not pressed in fully, the machine thinks that the grass collector is off, and therefore stops the engine. I had the same problem. If you take the grass collector off, you will see the button on the top left side of the back of the mower. It is covered by a strip of black plastic that slots over it.

To fix the problem my first solution was to tape a washer onto the plastic strip, thereby ensuring that the button is pressed fully in when the grass collector is on. When I got tired of the washer continually falling out, I used a screw to jam the button in. You should be aware though, that with the second method you will be able to engage the cutters with the grass box removed. Potentially a small child (with long arms) could put his/her arm down the shute and chop fingers off etc. I have no kids, and thereby feel safe.
