the IDE options Indicate that you are relying on some developers method.
Many developers have caught redmonditis and added things they "know" you want. Do you have the ability to see the final product in a simulator or emulator ?. If you do, try to follow from the 0 address. I do not see how it can be a power problem, unless the chip battery is defective, battery backed NVRAM will lose a location or two if the cause is power up/power down.

Have fun,
