Fuel filters would be the first step. Much smoke out the pipe?

gas or diesel ?

[adamanderr]

diesel .a bunch of whiter smoke towards the very top of hill but real light once warmed up.i might change the fuel filter(S) again see if it helps. but i did replace them new napa. about 6000 miles ago so id think theyre pretty good

Sounds like a fuel delivery issue, definatley start with fuel filters, what engine do you have?
