Maybe you are browning out due to inadequate power supply
I checked that also with my scope. Power is solid.

I am using a 2A DC/DC converter PT6212E-5 on my circuit board with plenty of bulk capacitance. I have used these parts on many of my other PIC projects without problems. I am using a 3S1P Lipoly battery pack that can supply 30A cont current for my 12V input until it can be installed. I am using PBP V2.46 with the patch installed and the latest beta programming software with my epic programmer. The epic software on CD V3.30 gives the same reset problem...
