2015 multiple electrical malfunctions.

First off I am new here and thanks for allowing me into the group.
I have a 2015 XLT 6.7 4x4 crew with 230,000km that was running perfectly when I parked it last night. This morning it wont crank, fuel pump doesnt work, blower motor doesnt work (on any speed), i have several warnings on dash including, service advancetrac, trailer brake control module failure.
I assume that I have lost power or ground to these functions. I have checked fuses both under hood and in cab but do not see anything that is burnt. nothing in the manual is labeled for this group of functions.
Its a long weekend and the ford dealer here cant even look at it until Wednesday. Anyone have a similiar experience that could help give me some direction as to what to check next?
Thanks
Dean

No experience, but if there are multiple unrelated failures, I'd look to grounding of the PCM and other computers (BCM etc.). If that ground connection goes bad and the ground floats up, you will light up the codes like a Christmas tree as everything else is referenced to ground.

I would check out the connector by the e brake if you use it often. Sometimes they come a little loose and wreck Havok

This was my first thought, I had hvac not connect and be inop until shut down and open door, then when turned back on it came on. Reseated this connector and thus far no issue, though I do expect it to come back at some point...
