That car can suffer from fault with wiring loom in engine , worth a look .Could also check wiring to engine temp coolant sensor for dirt/ corrosion and also earth wire from engine / gearbox to body .This answer from another forum explains wiring loom problem .
The wiring loom drops down from the fusebox and is bolted to the gearbox. As you pull away, the gearbox [and engine] move on their rubber mountings and flex the wiring.
Corroded connexions [or rotted wiring] are very sensitive to tiny movements; they can be enough to make or break poor electrical contact. Slight variation from heating up can cause similar effects.
The loose steel crash box over the ECU that's bolted to the back of the engine [just about the most imbecilic place you could put it!] will be chomping merrily through the wiring loom by now, so a new engine loom is usually a matter of when, not if, on these. [Or even "when did it last have a new one!"]
These sorts of faults bedevil the Clio II - the dealers fit dozens of new engine looms every week. They literally rot away.
