Hi dmairspotter,

I think you may want to put a few more capacitors on your circuit. Put a 10uF on both sides of the voltage regulator along with .1uf caps. Put a .1uf from MCLR to ground. Then try your power off and on again and see if this doesn't clear things up for you. It probably wouldn't hurt to also put a 100uf on th inout side of the voltage regulator also.
