Engine/Transmission (1998.5 - 2002) fueling box trouble!

[NScott]

Recently we towed heavy from Indy to Nashville and our "box " seemed to work ok going up but on the way back the box seemed warm to the touch and it "cut out" (cycled off and on) about every 20 to 30 seconds. When it cut off, my boost would drop off by more than half and the truck seemed to have the power of bone stock or worse. Has anyone else experienced a enhancement box that has given this type of trouble

Any ideas or comments are appreciated.

What kind of "box" are ya running ? Sure sounds like a weak connection to me. Are you tapped into the VP44 wire using a scotchlok type connector ? If so, that would be the first connection I would check. If all electrical connections are tight and you are not throwing any codes ( MIL light) you might want to start looking at your fuel pressure. If your FP is strong while under sustained throttle/load and all of the above are okay, I'd pull the "box" and send it back to it's maker for tests.
