I've got a problem with my truck that is really getting me down. I
tried taking it to a shop, but they told me that they have to see the
problem in order for them to know how to fix it. And maybe that's
true, but the problem only occurs sporadically. Let me see if I can
adequately explain this.

If I take off too fast or stop too quickly & take off again, I run the
risk of having my entire dashboard go out. My truck will still run and
the radio, signals, and headlights still work. But the speedometer,
odometer, gas gauge, heat gauge, etc... either goes straight down (the
needle, that is)...or just freezes in its current position. The
digital odometer either shows a mangled reading or no reading at all.
If I continue to speed up when this occurs, estimating at about 55
miles an hour, my truck will start cutting out. It won't shut off,
it'll just cut out. The gas pedal loses all pressure until I reach
about 40 mph (again, I'm estimating since I don't know how fast I'm
going at this point). Once I get around "40" again, the pressure comes
back and I can accelerate a bit more. But, if I accelerate a little
bit too much, I end up in the same situation (i.e., the gas pedal
looses pressure and my truck cuts out). This is very embarrassing in
traffic. And this cutting out can also occur if I take off too fast
while my dashboard is experiencing its moment of dementia. It's as if
the dashboard going out triggers my truck to start cutting out if I go
over a certain speed.

I put a machine on it to see if I get any readings...and the only
reading I get is a Knock Sensor malfunction. Now, could this be
causing my problems?

I need some help, not a lecture in "Duh! The diagnostic machine says
it's the Knock Sensor...so, change the Knock Sensor!" That may be the
problem & I plan on doing that. But, I would just like to know if
anyone has ever experienced this before and what did they do to solve
the problem?

Any insight would be greatly appreciated!

Thanks guys.
