That power reset after programming the PLL bit me a couple of times
here. Note to anyone using the ICD2 - be sure to power off your target
circuit AND pull the RJ-45 connector from the target circuit after
programming the PLL. The ICD2 will still provide power to the chip after
your target power is removed.

I have been using resonators without external caps. I'm running a 10 MHz
crystal on an 18F452 with 22pf caps. The chip won't run without them.
Maybe there is enough stray capacitance on the breadboard to get your
clock running?
