Thumbs down Hesitating at WOT 5.0l Mustang Plz help

I'm have troubles with jamming on the gas and getting good acceleration at WOT. Seem if I take it easy on the throttle I get great pick-up but if I pass a certian point ,say a little more than half WOT, the acceleration seems to hault for a sec then jumps back into acceleration after I let off a little. I have brand new 24lb injectors, new fuel pump, absoulutley no vaccum leaks, new adjustable fuel regulator set at 48psi (seems to run good there), Trickflow Twisted wedge heads, and edelbrock performer intake, & 73MAF. The computer is throwing one code that says ROM failure or "keep memory alive failure". Is this something I need to look-in? Any help from all you ford fans out there will be greatly appreiciated.
