May or may not be relevant but a similar problem with my Honda, it was the ignition solenoid dry joints, would always start from cold but used to crank and not fire when I've done a few miles, leave it for a few minutes and it would fire up straight away, just took it out and soldered over the joints. Cheap so maybe worth a try.

 

I'm not that far away - about 60 miles in Chatteris, Cambridgeshire. If you want to save the price of a garage and fancy a trip into Fenland you are more than welcome to pop over.

Now there's something to check, Relay, Relay for the fuel pump. Just reading an article regarding a Volvo 940 where it would suddenly cut out or wouldn't start at all. Was a fault know to the trade it seems, don't tell anybody else it seems. The Relay for the in tank fuel pump was found to be the fault. Dry cracked joints on the contacts, resulting in conditions when it would start, others when it wouldn't start. Temp of Relay may cause that. Easy check with spare or new Relay.

After a few weeks trouble free motoring the car wouldn't start again, AA man checked and no stored codes but the coolant temp sensor was reading 218 and the intake temp sensor 218 as well, the engine wasn't running. I'm thinking a wiring problem?
