What makes a 1999 Pontiac Montana van engine stall while driving?

My 1999 Pontiac Montana would seem to "skip a beat" while driving. It then started stalling and restarting, all while driving at highway speeds. My mechanic found that an electrical cable that carried an engine sensor signal was leaning against a hot part of the engine. The cable insulation had melted or worn through, causing intermittent shorts. The shorts confused the engine computer, which then stalled the engine. He simply rerouted the cable and all was fine after that.

You are not giving enough information to get a reasonable answer. It's like asking why it won't start. Any, and I mean any, detail would help. Are we talking about the engine cooling system? What are the symptoms that bring you to the conclusion it is overheating? Have you checked the coolant level? What year and size engine? Does it overheat only when stressing the engine, like climbing hills? Does it overheat only in traffic and okay on the highway? Does it overheat when the car is idling? Has the head gasket ever been replaced?
