I've got an ex mod 90 that I fitted a 2.5 petrol into to avoid the dreaded LEZ.
Ever since then I have had problems, generally in hot periods and in traffic where the fuel pump gets louder and louder and then it cuts out. Leave it for 20 minutes and it will run again. Temp gauge works and is not showing engine temp too high. I have now spent a fortune on this with reputable LR specialist who do this and that, say they have tested it, (usually in country lanes with no traffic), and tell me it won't happen again. It makes the vehicle so unreliable that I hardly use it. It even happened whilst idling at its MOT!
Tried to start today and now have fuel pump ticking ver, very loudly but won't start. Any ideas on the whole saga would be great, I don't really want to sell.
Many thanks

Tried fuel cap off?

Did you fit the insulator block between pump and block ?
It sound like fuel vaporisation , just get a facet electric pump and fit in line between tank and lift pump , when you get a engine stop , switch on pump wait a few seconds and it should start right up HTSH

fit it down by tank .

Many, many thanks, much appreciated. I had Gigglepin fit the engine and they have looked at it since, changing this and that, but no one ever suggested this.
I'll get straight on it.
