Do your mechanics know anything about Classic Minis? Most just chuck new parts at it at your expense!
It could be several things. You have to go through everything methodically.

check that there is actually a spark from each of the leads

Hi John / Dominguez
Here's what I would do;
Listen for the high pitched sound of the fuel pump when you turn on ignition - no sound = fuel pump problem
Turn over engine for a few seconds - f you've got a spark tester you can do this at the same time - then take out a spark plug (turn ignition off for safety).
Check to see that the spark plug is wet with fuel - you should be able to feel it with your finger & smell the petrol. No fuel here = fuel injector not working (could be a few reasons for this - e.g. main relay / fuel cut off switch (as southlincspickup says) / wiring).
Note* you can take off the air filter housing and see the injector squirting when you look down the throat of the throttle body, as the engine is being turned over.
If you have,'t got a spark tester, you can do it now - get someone to turn over engine with the spark plug you've just taken out pushed back into the lead and outside part of plug resting on engine, to make contact (earth) with something bare metal e.g cylinder head stud. You should see a spark (easier if it's a bit dark).
No spark = ignition fault e.g. coil pack / distributor / rotor arm.
Note* on injected minis the distributor only distributes the spark, it's timing is controlled by ECU & flywheel sensor, so worth checking these connections, which will mean no spark is sent to the distributor. Again, a spark tester is invaluable here.
If all of these seem fine, I would suggest a cylinder head gasket failure, going by the story of how it stopped during the drive. A compression test would be wise before starting any dismantling though.
Good luck!
