Use your LEDs

Indicate phases of program operation by illuminating LEDs. In particular a lot of electrical faults cause the PIC to resst. The first thing your code should do is illuminate a "startup LED" for 100mS. If you see that LED flashing repeatedly, you'll know your PIC is reseting.

Why is my PIC reseting?

Often from spikes. Add more 1uF capacitors near your digital chips, especially H-bridges.

Runs only with ICD unit attached

Make sure you are not in debugger mode. Try adding the NOBROWNOUT fuse at the top of your code.
