Injector Pump ?

. Been having a strange problem for some time and have replaced just about everything and still does it. . 2002 - 2500 automatic. . Runs great for about forty five minutes then developes a momentary power drop when holding a steady speed. . . . It will momentarily loose power then pick right back up. . Does this at regular 6 or 7 second intervals. . Will excellerate beautifully then resume it's pausing again when you level off at a steady speed again. . . .
TPS replaced three years ago. .
Manifold pressure sensors replaced six months ago. .
Trans transducer replaced two years ago. .
ECU replaced this year. .
Has two transfer pumps, pressure is actually a bit high. . . . .

Yup. . Does not do it while excellerating but no matter what speed you level off at it does it. .
