Brian, did you try the spare clock? That was my original which I swapped out when trying to find an electrical fault on mine (ABS light) but it made no difference therefore it wasn't the clock in my case. I'd also be surprised if the clock was the fault with yours.
My own 2p is that it's likely to be related to cables at the starter motor because the issue as you describe it occurs at the point of trying to start the car. The connections at the SM can get very corroded. IIRC there is a big earth strap that goes to body behind the start motor which is also highly exposed to corrosion. Maybe it's even the starter itself that is causing the issue.
