Hey everyone.
I am having an issue with a GU 98/99 4.5 petrol injected.
Its running fine around town, out on the tracks no worries and doesn't seem to be down on power. BUT.......
When we take it up a good size hill run it will run fine with plenty of power for about 1/2 to 1 minute and then start to sound and feel as if its running out of fuel. It doesnt ever stall just looses power.
(FYI) - This truck has a 6" lift with 35's. no mods to the engine other than the exhaust.
My thoughts are electrical rather than fuel or pump as it does it when the tank is full or half full.
Lend me your thoughts.
