OK, this is not going to be much help. I'm running on too little sleep again, and I am not all that familiar with your model truck.
But, one thing stands out for me, and maybe if I show it to you, you can take it from there.
You said that the remote starter has its own positive feed. Obviously from the battery, but where does it tap off from? And what does it feed when it cranks the truck?
It would seem that your trouble is between those two points.
Actually, it sounds like your alarm might be causing the problem. Most of those will kill the ignition and quite often the starter when tripped. I am thinking that whatever kills those, probably a relay or two, is not working right.
There is a point I am trying to make, and I sure hope you see it, because I lost it somewhere.
I'm going to bed, hope you get it going. After a couple of hours, I will look at it again and see if I can post something more coherent.

Thanks for the try.
The alarm is fed directly from the battery, to an auto circuit breaker on the firewall, then to the alarm box. The alarm feeds both the ign wire, acc wires, and start wire to start the truck. There is a starter kill relay, but even if that was messed up, the key would turn the ign on, and the power door locks, etc would still work.
ALL elec systems original to the truck are dead. They only work when the ign/acc wires are being fed by the alarm when the truck is running from a remote start.
So yes, you are correct in saying the problem is between the battery, and the truck fusebox. I'm trying to figure out exactly where.
Batt feeds to starter, and back of alt. Main starter post feeds a red wire (with a tested fuseable link), which feeds somewhere. I think to teh fuse box. The problem has to be downstream of the tested fuseable link, between it and the fusebox. Maybe ill crawl under the dash, and try and disconnect the fusebox as a whole. That, or jiggle wires under there. At least with the key left in teh ON position, i will hear the ign circuit come on with the seatbelt chime, etc.
I'll try and play with it more tmr.
