I forgot to mention that on the second breakdown the car was stranded in a car park. Jumping did not start it, but a 5-litre can of fuel did seem to do the trick. The car does have have about 20-30 litres in it now though.

I'll have to do more investigation into the connections then. I took a look, but the negative and ground connections did look ok. Will clean and re-seat them.

My bet is on the fuel issue. I had all the warning light issues you have had but that was due to leaving the car for 5 weeks so the battery was low attempting to start the car with the fuel supply issue drained the battery even further causing all manner of warnings to appear.

Yes, I'm wondering if I do have two problems now - the flat battery from attempting to start the car as you say, and the fuelling issue which is the real culprit.

If I stick my ear right over the pump cover when the ignition is turned to the first position, I should definitely be able to hear something, yes? Tried earlier and couldn't hear a thing there or behind the cap.

So I've replaced the old battery, which has made starting much easier. I also filled the tank to the brim to test whether the problem only happened below 1/2 a tank as many people have experienced. I managed to go about 70 miles of mixed driving with nothing at all wrong yesterday, and then had a ten minute stretch of the car stalling, being difficult to start, and having a very lump idle. Not sure if it's worth noting that the revs won't drop if my foot is on the pedal, and I can prevent it from stalling by holding it.

My plan this weekend is to look at/reseat/change/clean the following:

Fuel pump
MAF
Fuel filter
Vacuum lines
Throttle body

Anything else I should be looking at?
