Technical Fiat Uno starting problem when engine hot.

[Alfaguy]

So I have a nice 1988 Fiat Uno 60S with only 6,000 miles on the clock. One thing that has spoiled my enjoyment of the car is that it almost always will fail to start if I stop the engine briefly when the engine is hot. It's not an overheating problem as the coolant temperature is normal. If I just leave the car for an hour or so to cool down it will start again without any problem. This means that I have to take it for a non stop garage back to garage drive. I had hoped to use this car as a nice classy town runabout on nice days but this fault makes that impossible.

What could be causing that?

Oops should have done a search on here - seems I am not alone with this problem.

Won't start when hot | FIAT Uno

got an issue with the 1.0 IE as per title won't start when hot. My MK2 will start really well, run all day, never stalls (well hardly ever :o:p) apart from if it's been at running temp and I stop for say 5 - 10 mins then try and restart. it refuses to start till it's cooled down. I assumed...
