Hi everyone new to site. I have a 1990 Ford f350 crew cab dually 5-speed manual transmission running into severe problems climbing any type of incline truck stalls and craps out. On flat and level roadway truck starts idles fine revs up to $2,800 RPMs $3,000 RPMs no problem as soon as the load is put on it dies. I replaced the fuel filter and the lift pump and still no solutions.any feedback or suggestions what I should look at next would be greatly appreciated.
