Not a perfect solution, but I probably did that 3 or 4 times on my '33, and its been on the road 12 years now.

I will check tomorrow. But when I first go to start it almost fires and then kind of seems like the ecm is shutting something down. Also, with key on the pedal accuates the throttle body so I wouldnt think my TAC randomly went bad. I haven't even driven the truck since my swap and literally every time I have gone out and tried it has fired right up with no hesitation and ran as long as I wanted.
