Update on my problem....
After reading the suggestions, I took my car to Halfords to have the battery checked and their little battery diagnostic tool showed that there was a lot of "noise" on the line so I changed the battery anyway although it showed no other signs of malfunction. At the same time I checked the coolant level and found it to be low so I topped up with antifreeze.
On the way back home from Halfords (about 3 miles), the car worked normally. This morning it did exactly the same thing again. However, now I have found how to duplicate the problem at will! If I accelerate "Rapidly" from about 30mph to about 50 mph a couple of times, the temperature gauge shoots up off-scale and the engine goes into limp mode. Depressing the clutch or putting the car in neutral and blipping the throttle a couple of time, the temperature gauge drops rapidly back down to normal and the car once again drives normally! The engine does not overheat when this happens nor does FORSCAN show any error codes!
Somebody somewhere must have experienced similar issues and have an explanation for this weird behaviour!!! I am getting to the end of my tether and worry every time I need to embark on a journey of any distance because I am losing confidence in the vehicle and do not want to be left stranded.
CAN ANYONE HELP PLEASE?
