Audi Repair: engine heat, audi v8, guge

Question
Sir,
i have Audi V8 Quttro 1990, it has been left long time ago without being used, now when i start its engine it would run very smoothly but after 5-10Km Temp guge would increse rapidally to reach up to 110C and here the engine will stop running suddenly and dashboard checking screen will read "Cut". some michanics said to me that the reason beyond that rapid accelleration of heat is the engine, there is no obvious reason for that temp increase. any way if i would wait for about 15-20 min to run the engine it would starts again but to stop after anthor 5-10 when engine heat start to elevate.  

Answer
hello
I used to have a mazda which was doing the same thing. It turned out to be a bad termostat. I think you may have the same problem. when it overheats check your hoses on radiator if top is very hot but lower is not replace termostat.
Good luck
