Lorn,
Like you, I often fly our 320 high (15,000 - FL190) for long periods of time. I haven't had this problem at all. Hard to understand how it could be a systemic problem when it occurs on yours but not on mine. I know that our planes are pretty similar and close in vintage.

I have determined that the problem is caused when the hydraulic
pressure at both switches is high enough that not only does the pump
not run but also high enough that when the dump valve is opened the
pressures are still not relieved to be below the pump run setting. eg.
If I fly high and the temperature on the ground, after landing, is 60
degrees farenheight more than the temperature in flight, the gear
won't go up on the next flight.
An EE friend of mine, after seeing our hydraulic system schematics,
talking to Lancair and talking to Oildyne, has come up with 3
solutions to the gear not going up and/or coming down. I am out of
town and haven't had the chance to see the solutions. Would anyone be
interested in a kit that solved the problem for $200 to $400.
