Problem when climbing hill

[bestes]

I have recently had a little problem develop on my 1992 Ford Ranger. I seems to lack a little power. It doesnt have the go like it used to. And occasionally, when Im climbing a hill, it will jerk like it is not getting enough fuel. It doesnt happen all the time, just every other hill or so. Could this be caused by the fuel filter. Im sure its due for a change. Here is the info on my ranger.

1992
3.0 V-6
Automatic

Thanks for the help.

check fuel pump pressure. I would change filter. just because your not sure when you did. it would long be overdue if not.

Also, when was the last tune up?

13 years old it prob needs alot of things changed or cleaned.list how many miles, how long you had it, what you have done as far as maintenance. is check engine light on? dose it come on when you turn on the key?(shows that it works)
