I would start with a new fuel filter.

I assume it is a diesel?

Yes it is a diesel. It is running good but won't go over 30 miles per hour-it doesn't make sense because it is running good. Where would the fuel filter be located?

Lift the cab and it should be on the frame rail. Could be on either side by the fuel tank.
