1984 K10 electrical Woes

[ackland3]

So i got my new K10 and on the way home stopped for gas and it wouldn't start no click on solenoid nothing at all and ended up getting towed home. Went ahead and replaced starter cleaned up some wiring etc. and no crank no start again! after hours of trying to find what was wrong I jumped the starter using a screwdriver and it turned just fine, crawled in and tried the key again for giggles and wouldn't you know it it started right up! any ideas on what it could be?
