Hello and welcome to just answer. I have seen this before and it is almost always a failing positive and/or negative battery cable. The cables develop corossion and or
loose connections at the crimp between the cable clamp and the wires in the cable. The fix is to replace the cables, however you may be able to buy some after market universal cable clamps and cut the factory clamps off and install the after market ones. Then when you get home you can replace the factory cable harness. This should get you back home.
The only other thing it may be is an internal problem with the PCM (engine computer). The PCM has the charging system voltage regulator built into it and sometimes they act up.
