I think you may have to change your spark plugs, wires or distributor cap. I damaged a spark plug wire yesterday while channgeing plugs and my truck did the same thing you describe. I don't agree with the above answer, as far as I know the Mazda B2500 is a diesel engine and therefore does not have any of the above mentioned things. Mostly likely things that could be causing jolts climbing a hill are the diesel fuel filter is dirty, you got dirt in the tank or the injector pump or fuel injector need to be serviced.
