1990 4.3L Mercruiser - cold start issue

[champlaindave]

Last 2 mornings, ignition and instrumentation not working. Turn key, no joy all instrumentation and engine ignition. Removed engine cover, pressed re-set on Mercathode and still no joy. Then, without reason, suddenly the instrumentation comes alive and engine is allowed to start. No further issues when running remainder of day - (note that engine is at running temperature rest of day.) Replaced ignition switch, did not fix issue. Thank you for anyone's assistance!
