What should I check when the switch is replaced but still nothing is happening?

I'm having starting issues with my 3.0LX Apha One. Using an old post about troubleshooting I decide it was the slave solenoid and replaced it. I tested it before going to the lake and the engine started fine. When we got to the boat ramp the engine started fine. I went to park the car and trailer while my wifed idled around waiting for me. When I got back to the ramp she was waiving at me from about 50 yards out saying the engine had turned off. Long story short, now nothing is happening when I turn the key. No voltage indication, no gauges coming on. I thought somehow now the switch had gone bad so I got a new one and it didn't fix the problem. Now what?

Check the battery conections

The battery is brand new.

Check the CONNECTIONS

The battery connections are clean and tight.

I followed the battery cable to a "box" where a bundle of wires comes out of. The red wire coming out of the box has a plug with a fuse in it. The fuse looks good and I got a light on my tester when i checked the plug that was coming out of the box.

can you locate the slave solenoid on the motor and the 50 amp circuit breaker(red button)

power originates at the starter and you need a good engine ground too. from there thru a 90a fuse link(white plastic block on the starters main post) thru the 50a circuit breaker , thru the harness[plug to the dash

the original problem was a click when I would turn the key. I replaced the slave solenoid and it started fine. Now I'm having this problem. I'm wondering if the 50 amp circuit breaker went bad somehow?
