Re: kinda cutting out a 45 mph for a second
One thing that i can think of is check pin grip tension at crank sensor connector, not likely if at a certain speed but who knows. Normally for something like that i would install a data recorder and instruct the customer to hit the button when they feel the problem it would then record data to be looked at by the tech.

If you can get access to a tech 2 scanner you could take a center triggered snapshot and record data that way. Center trigger will capture data before, during and after event to be compared

Re: kinda cutting out a 45 mph for a second
It's like it loses ingnition for a spit second today it did it at 25 mph then it goes on like nothing happened ! All gauges and electrical stay the same except the tach drops about 1000 rpm when it happens and its only for a second or two and its over !

Re: kinda cutting out a 45 mph for a second
I've had this same problem for about the past 6 months. Still haven't figured it out. The old service manager at "Hummer" thinks it's my torque converter, or something else in the transmission. We did all of the normal stuff, such as injector cleaning, etc., but nothing changed. I'm just waiting for something to finally break, then I'll know for sure what it is.
