I'm running an SX48 and everytime I try to run code with the 50MHz resonator everything crashes after about a minute.  The code will run fine if I generate the clock signal from the SX key and have the resonator disconnected.  I've checked the resonator circuit many times but I think that's hooked up right.  When I try a new resonator it will crash after a different amount of time.  I'm pretty sure the resonator itself is fine because it works fine on a development board.  The code I'm running is simple.  I've included a schematic of my resonator cuicuit and the code i'm running for reference.  Has anyone experienced anything like this before?  Any help would be greatly appreciated.
