@JPMC-
It would help those who wish to/could help you, if you told us the year, mileage, options, trans type and overall condition of your rig:thumb:
Help us help you by providing as much info as possible.
To get to your fishing hole did you travel down a bumpy road, ford large water holes, anything like that? Is the starter clicking at all do the gauges and dash get power, or does the dash seem dead? Do you feel like it could be a mechanical issue or maybe just an ignition relay, electrical? Did You check to make sure all the major under hood connections are good, like ECM, TCM and BCM? You said the batteries are hot, I would assume you mean they are charged, right, or are they physically hot?
Taking the time to be more literal and thorough in text will help as well.
