This intermittent problem may be with L15 - wonder if wax is clogging up the coil and changing the results you get once it warms up,

So I'd check for heating - on the FOIL side - feel for warm spots - shouldn't be any, but if caps are bad or you have wax and debris caught up in the wax - changing resonance - which can happen due to age and dirt - even the tuning cap below the slug can fail - intermittently due to wax creeping in and flooding the cavity - even if there is no cap there

schematically it shows there's nothing there - but even then debris can cause tuning issues with old wax.

IT may need to have L15 taken out and cleaned up - check the bottom "tuning" cap area - if its' crushed, there's' the problem, the slug tuning deformed the coil to a point where it can ring in specific points but simple time and vibration will make the slug to coil aspect tuning shift and you lose resonance..
