Mercedes CLK 320 cutting out when hot

[MBW208]

My CLK 320 sport has recently developed a serious engine failure problem - engine cuts out when temperature gauge reaches 80. The problem has got gradually worse in subsequent weeks to the point where it is currently confined to the garage :-/ The car will ALWAYS start from cold, however dies after less than half a mile. Engine turns over but will not fire until it cools and temperature gauge drops below 60 and away you go again.... Sounds like a temperature/ coolant problem. I'm hoping it's only a temperature sensor or something similar. Plenty of coolant in the tank and no apparent leaks. Any ideas anyone???

Sounds like a faulty crank position sensor, a common problem on the V6 engines ,do a search for recent posts.
Easy job to do and not expensive. No.5 on this diagram;http://www.detali.ru/cat/oem_mb2.as...GA=722.607&CT=M&cat=19Y&SID=15&SGR=075&SGN=04.
