I already tried that and the battery is fully charged so I'm not sure what else it could be

 

You checked the condition of the cables at the starter and engine block?

 

I've checked the battery terminals but not the started block

 

How are you so positive the battery it's fully charged? You mentioned you get headlights but you can still have lights but almost no charge. So did you test the battery or are you just assuming it's charged because last time you looked at the gauge it said it was charging?

 

We tested it and charged it so I know it's full

 

Then if it were me, I would check all my main powers and grounds and all the fuses in the power distribution box and Just for fun the kick panel fuses

 

I checked all the fuses but haven't checked the main power and grounds I'll do that as soon as I get home

 

I replaced where the ground wire hooks up to and replaced mybbattery terminals and some of my relays and still nothing happened

 

Starter relay(small silver thing next to the battery), but I am a thinking more like the ignition switch on top of the column.These like to burn up.
What was the last thing you did before it died?, turn on headlights,radio,blower?

 

Nothing, I had been driving over 20 miles before it died and I replaced the ignition coil a couple months ago. It could be the starter relay but would that cause it to just shut down??

 

Not the coil, Ignition switch... This going out can cause you to lose all power to anything that runs through it; radio, headlights, blower, starter...ect.
It can go out while driving or upon start-up.
One of the connectors likes to short out and melt the switch and plug.
Located on top of the steering column under the dash it is worth a look.
I do believe the relay can also cause this, but Cruiser may know more there.

 

Like here?

 

I checked the relay and replaced some things but I'll check the ignition switch tomorrow thank you

 

If it is the switch specify tilt or not when getting it. Both switches work but your key will work backwards if you get the wrong one.

 

I don't really understand what you mean, what do you mean by specify tilt
