Today I go to the garage & removed my Redline box. I just unplugged it from the injection pump wires [spade terminals], then pulled it back through the firewall. I started my truck & set warmup mode to 140* & high idle to 15sec.. About 5min. later, I hear it shut off. I go to the garage & try to start it, fuel pump isn't running? I checked codes & got 1693 & 1691. Smarty was on sw4. I checked the fuses & connections, all is well. I try to start it again, fuel pump is running & it fired right up. What can cause this?

I drove to town after I got it running & everything was fine all day.
 
My truck will do the same thing. But sometimes it will die right when it idles up and other times it will die whenever. Usually to get mine to start back up, i have to unplug the box for a few seconds and it'll fire right up.
My truck also started dieing when at higher engine speed. Like at 3-3300 rpm. All i have to do is unplug the box and it'll fire right up. You can crank and crank on it and it will never fire up. I don't know what the deal is....
