Hi,

I read your original post again, and I wonder if are getting a
watchdog reset every 15ms. Sounds unlikely given that you have
the watchdog turned off, but worth checking.

Another idea, what kind of oscillator are you using? In general, the
PIC oscillator requires careful attention to layout, crystal type and
capacitor values. A lot of the time they work with any old crystal
and caps, but sometimes they can be stubborn and refuse to start
or are unreliable in operation. Keep the crystal and caps or
resonator PCB traces very short and not too thin, and add a GND
shield trace around it if possible.
