Theft Light Flashes After dSsarm, Won't Start

Driving along truck just shuts off, won't start. Checked everything. I think I have it narrowed down.
The Theft light flashes every 2 seconds. It continues to flash every 2 seconds even after the system is disarmed. I have tried everything in the owners manual with the key (coded original key) and the keyless entry disarm code. I can arm it by pressing 7/8 0/9 and it appears to arm (lights turn off, theft light flashes every 2 seconds). I key in code to unlock doors and disarm, Theft light just keeps flashing.

So it appears the Anti-theft system is permanently tripped, thus it won't start.
Any help would be appreciated.
