As a temporary fix I put a smaller extra solenoid (marine rated) next to the starter that is activated off that wire from the key, that in turn energizes the main starter solenoid. The real fix is to run a new heavier wire from the key switch to the starter solenoid, but my 'temporary' fix is still working fine after about 19 years.
A friend had the same issue, he ran a new wire. Neither of us have had a problem (that one anyway) since.
Verifying that the ignition key and wiring are providing the proper 12v "start" signal to the solenoid is certainly something to do when troubleshooting. Well in advance of parts swapping, obviously. However, based on the symptoms described (below) it is clear that there is a problem in the primary voltage path (battery to starter).
