Interesting to hear your problem...Have you high pressure washed the engine bay recently?
I had a similar problem with a 156 after washing the engine. It turned out that water got under the "bolt on engine cover" and filled up the socket that holds the spark plugs, thus interupting the power supply to the plugs by shorting out. The first time this happenned it went away after a few days when the water evaporated but the next caused a complete stall on the motorway.
I havent had this cover off the GT yet but if it is the same design, then could explain your problem.
