First TVR 'moment'
Discussion
Just popped into town to get some stuff. The traffic was a bit stop start. Anyway as I'm still new to these things I was keeping an eye on the temp while crawling & it gets up to about 90 & sits there. I stop at some lights pull away & notice that it feels a bit rough. a few seconds later it just dies so I pull over. turns over fine but won't start. I remember reading that you need to wait 30 sec before restarting so I do & it fires up fine & off we go. 1 mile later same thing happens. wait a minute & off we go. I'm thinking vapour lock
Do they suffer from this?
Is it likely to be something else?
The temp never got near the red.
Maybe I hurt it's feelings using it as a shopping trolly!

I do not believe that fuel vapour lock is likely to be the problem. However, were you low on fuel at the time? The TVR petrol guage is not known for its accuracy and you may simply have had fuel pickup problems from a nearly empty tank.
If the problem is down to heat, the things most vulnerable under the bonnet would be the ignition coil and the module on the distributor.
When the engine refuses to restart you first need to keep a carefull eye on all things electrical.
If the problem is within the electrics you might notice that other things like the dash lights or rev counter don't work. These clues help identify the possible fault area.
Next to consider might be loose connections or relays resulting in intermittent contact in the engine management and alarm wiring area. Most of this is found in the wiring loom jumble that lives above the battery in the passenger footwell. Attempts to start will sometimes shake things about and remake any dodgy contact and everything works again.

If it won't start, switch the ignition on without trying to start it and listen for the sound of the fuel pump running (it should run for about a second after you switch on). If you hear this you know the fuel pump is working and the problem is probably elsewhere (the ignition would be the next suspect). It may not be easy to hear if you're somewhere noisy, but if you can hear it that's one less thing to worry about.
I'm 99% sure it didn't overheat. The guage has been higher than that when the weather was warmer.
It was on part/trailing throttle (20 mph ish)when it died not idleing.
When I tried to restart without waitng 30 sec or so there was no fuel pump noise. After 30 sec the pump came on again. I may be wrong but I,m sure I read that this restart delay was built into the ecu to protect the cats from unburnt fuel. It fired up instantly & ran smoothly.
Is it possible that the fans kicking in could some how cause the motor to die? The temp was about right for them to come on.
Help!

Cooling system? - No
Fuel system? - possibly. Sounds like it's not the pump but do check there's fuel in tank.
Electrical system? - possibly. If there are other electrical problems as well then it may well be.
First step is definitely to try to find out which of the two it is, fuel or electrics.
