    Lightbulb oscillator problem

    I'm running an 18f1320 at 40mhz using a 10mhz crystal with PLL enabled.

    The oscillator worked fine on a breadboard, but when I built a PCB for it, it worked for a while and then stopped working.

    It works again for a little while if I melt the solder points for the oscillator with my soldering iron, but 20 mins later it stops working again.

    Ive attached the PCB design. Anyone have ideas?
