Technical 500 TA stalling and not restarting for 30minutes

*should* get a code logged for that as the engine management would see the cam sensor, but not the CKP. But, yes, it's a good first place to look.

Not necessarily, it may well see the sensor, just not any recording from the sensor pickup, won't necessarily assume anything is wrong, just the crank hasn't turned.

But it will see a change in state of the cam sensor reading as the cam is turning. Generally, you'd assume that OBD will be able to ascertain that something's up - but not always; which is why I suggest taking some datalogs.
 
Now this is going over my head, I'm not as technical as you guys are. I will let you know what the dealer says. Should hear something in next couple of days, will keep posted in here.
 
Exact same symptoms we experienced on our Hyundai Getz. Actually happened twice on same car. First time fixed under warranty, then by myself.
Called the RAC out first time it happened and his diagnostics test was a bit vague and between us we guessed it might be the crank sensor. We thought the car was out of warranty due to doing my own servicing. However, when I telephoned my dealer to order the part I was advised my car would be repaired under warranty. What fun we had taking the car into Glasgow, about 40 mile trip. Car would stop every few miles, pull into hard shoulder and wait for it to start again. Disconnecting the battery for a few minutes always seemed to help.
Anyway, avoiding a long story it was the crank sensor, and it went again about a year later and I fixed it myself. The original replacement had been poorly fitted and was destroyed in situ by moving engine components.
Just read the OP again, and driving slowly did increase the chance of stalling. Keeping the revs high did put off the inevitable stall for a wee while longer.

You said the starter clicks. Does it mean starter is running together with the engine as usual or not?
Did you try, in case it happened, to diconnect the battery (very easy for TA) and to reconnect after some minutes to solve the problem? If this works, it could show that it is not a mechanical poblem.

Well I promised I would update you all with my ongoing problem so here goes.
It's now March and the problem is still not fixed!
The dealer has been very supportive, unlike Fiat UK.

The problem has now been experienced by the dealer, once while the mechanic drove and once whilst me driving him.
I now know it only ever happens ( with OR without start stop engaged) only when the 3rd 'blob' on the temperature gage is alight ( no other time) and when I have been in 1st gear or stationary in heavy traffic crawling for 5 minutes or more.( once the 4th temp 'blob' is alight or when the engine is cold it does not happen.
The engine cuts out and it's takes several attempts to start, not the 30 to 40 minutes it did in the beginning of the problem.

The dealer has involved a TSAO case with the Fiat technical guys.
A coil has been replaced again and plugs, still it did not fix it.
A new RPM sensor was replaced and still the problem continued.
The stop start sensor was then replaced. Guess what? Yesterday it stalled again( 3 'blobs' alight.

I have noticed and explained to the mechanic that when it doesn't stall, I have noticed a loss of power when pulling away in first gear ( again only ever at the point of the 3rd 'blob and no other time) this feels to me that it's the point it would normally stall but seems to keep going if that makes sense.

It has to do with that point of the 3rd 'blob' temperature thing??

I'm getting desperate now, I dread my drive home in peak time traffic and am starting to hate the car.

The Fiat technical guys can't see it until the 10th April so it's booked up for then. Maybe a sink hole might swallow it up, I don't think I would be that upset!
 
Could it be something as daft as a duff coolant temp sensor or a software (maybe the fuelling map is boogered around mid temps which would match your lack of power? Although my electronic engineering "bits and bobs" tells me that's unlikely, but stranger things have happened. Might be worth a reflash (if it can be reflashed)) or hardware problem with the ECU.

Good to hear the dealer is trying their best. Must absolutely suck for you though

By this point I really think Fiat UK should've offered a replacement car. Not necessarily new, of the same age would be reasonable given it's age. The car could've been taken away, fixed and sold. Being a 500 with good residuals and high mark-up, Fiat probably wouldn't have lost much, if anything.

It's things like this which mean other equally troublesome manufacturers have a good reliability reputation & Fiat continue to have a patchy one - the good manufacturers don't leave their faulty products with the customer to suffer for weeks on end whilst they scratch their heads.

Take note, Fiat UK.
