I hooked up a tc lock switch using an E clip aka jesus clip took it for a test drive and throttle cut out had to press the throttle twice to get response again then the truck went to limp mode so I removed it found the e clip damaged the b11 wire so I soldered it disconnected the batteries to reset the computer hooked them back up still cutting out and going into limp mode so I removed the pin from connector cut wire back to fresh undamaged wire installed new pin so it is like factory reset the computer still cutting out and going into limp mode the only thing I figured out is that as long as my tc dosent lock for more than 20-30 sec it wont cut out and go into limp mode anyone that could help it would be appriciated

Well, your lockup switch and the wiring problem can affect the lift pump operation- but in your case I think it was just "running out of fuel" due to the higher demand on the engine during lockup.
If you read around here you will find a lot of articles and posts on monitoring your fuel pressure because the lift pump and fuel pressure is the achilles' heel of the 24V trucks.
