Check your battery posts. They are the usual dirty suspects.

If it is not the battery post’s check body to frame ground connections. Had mine rust and break.

Batteries can break down due to heat, and seeing that you're in TX, that could be the case. In AZ, a battery typically last 2 years regardless of car make and I've had mine fail while running errands. You might get some power for accessories but not enough to start the H3.

Another item to check is the wire loom underneath the fuse box by the battery. If that fuse box has ever been pulled, sometimes the connector isn't reseated properly or connectors break.
