Hi,
When you turn the key when does the power cut off: at ACC, ON or Start?
Customer: replied 1 year ago.
start
Expert:  Doug replied 1 year ago.
Thanks.
If you unhook the signal wire from the starter (the small wire that slides off), does the problem still occur?
Customer: replied 1 year ago.
yes
Customer: replied 1 year ago.
when I connect the OBDII there is no power received. However there is power to the instrument panel, radio, fan, and lights. In which at one point I turn on the fan and power went out.

Hmm, that is peculiar.
Looking in the under hood fuse panel, can you please inspect each of the large fusible links and the large link on the battery if still present? We want to check them for power and wiggle them a bit in case we have a hairline fracture passing slight power.
Customer: replied 1 year ago.
yes I have already check fuses and all fusible links.
Expert:  Doug replied 1 year ago.
How certain are you that the battery is good, was it actually tested (I know you mentioned it was replaced)? If so, what was the CCA reading?
Customer: replied 1 year ago.
its a new battery the old one was shorted.
Expert:  Doug replied 1 year ago.
And we are certain that whatever damaged the old battery has not affected the new battery?
The concern here is that there is no single device that is going to cause power loss like this, you are pretty well reduced to battery, switch, or fusible links/connections.
Obviously if the battery is weak you would have this condition, and letting it rest will let the battery stabilize and return to previous condition. If the links have tiny fractures they will do this as well, and after they cool they make enough contact to power up the low amperage items again. Of course the ignition switch is self explanatory.

Thank you for your time I will double check these and get back to you.
