Have you considered measuring voltages to see where the issue might be? Use the battery negative as the reference and measure the voltage on the chassis, starter solenoid, and starter. That would give you a lot of info on what is happening. A few DVMs would cost you no more than £30 and if it happens regularly it won't be long before you see it. If you get stuck let me know and I can lend you a data logger to log the voltages during cranking and starting.
