Think you'll find on that engine it's fitted into the gear box at the top towards the back,
signal taken from the flywheel.
Anyhoo take it out and clean any crap off it,
the thing is an electromagnet so they can come out looking "hairy",
Two wire device with and this is important an elecro magnetic sheild which sounds cool but is just some metalic silver paper covering the 2 wires then insulting over the lot.
The CAS or speed sensor or whatever Peug Cit call it is just a coil of a lot of thin wire,
The flywheel spinning past generates an A/C signal until there's a gap on the flywheel teeth and the signal "blips",
TDC CYL#1 which in French is the Cyl nearest the box.
So anyway if there is any kind of heat generated open circuit in the CAS obviously when it's hot the signal just drops out until the CAS cools down and the coil then works.
Soooo back to my O/P,
Maplins or any other electrical parts supplier sell "freezer spray" for a tenner or so,
When next it fails you've found the CAS and can keep spraying until there's frost on it,
You won't harm it,
If it then starts up you've identified a heat generated open circuit in the CAS.
If I'm wrong your down 10 squid.
