We have replaced our fuse box relays and fuses and wiring and fuel pump.

Car dies while driving sometimes I can put it in N and restart but other times I have to stop and let car sit for a few minutes before it will start again. When I try to start it after it has died it will try to start but makes a weird clicking sound.

This can be a clue that the battery is shorting out internally, so I would start with a new battery. If the battery warning light is on while driving this can be the alternator is not charging the battery as well. If the car is still doing it after the new battery and the alternator is charging, the most popular items are the fuel pump, crankshaft angle sensor and ignition switch. I can be many thigs causing this but we can run them down one at a time, I am here to help you :) Please watch this video to help us get started.
