hi i have a 94 f-150 4wd with the 4.9 .it runs good but if i park it on friday after work and dont drive it until monday morning it gives me some trouble . it will start fine and idle fine . when i go to drive it i can shift thourgh all the gears as long as i dont go over half throttle . if i give it too much gas it will bogg down and not want to put power to the ground . i have a seven mile drive to work and it will do it the hole time . after work it drives fine and it will drve fine for the rest of the week .then it will sart all over again if i let it sit for the weekend .

any help would really help , thanks

That is weird. I would attach a fuel pressure gauge to it and watch what it does. Check your voltage out of the alternator. Just to start with.
