Question about 2005 Ford F 250 Super Duty
Three times in the last month the truck would not start. Each time was after driving for about an hour around town. the truck will crank, but will not turn over. Just before it happened the third time it sounded like it was going to stop running in the intersection. I would push the pedal to the floor but the engine would not engage for several seconds, then would run very rough. The first two times, I was able to start it after approx. 20 minutes and several tries. the last time I had it towed to the dealership. It sat overnight, and when checked the next day, of course everything is working perfectly. Dealer says they cant help me because everything is working fine.

I had the same problem with My 1990 F150 300 6cylinder 4x4.....I cahnged all the same things you did, finally I sprayed a can of Gumout through the throttle body and it worked and ran great. Now I add fuel injector cleaner to the gas and a regular clean with the gumout and the problem has'nt come back. Good Luck to you and hope it works!

SOURCE: F350 don't start
Check to see if you are sucking air on the inlet side of charge pump, Disconect feed side of charge pump, fabricate a hose to place in a clear container to check for good clear flow.Hope this helps.

I would try replacing the wiper arm itself and also make sure that there is no binds in the motor or rubbing anything inside the door

It could very well be a restriction in the exhaust like a stopped up cat converter. I doubt if it is a torque converter,that may make it slow to get to speed but shouldn't effect hwy speeds.
You can check this vehicle for an exhaust restriction very easy by going to the DPFE sensor and measuring exhaust back pressure with a vacuum/pressure gage. It will be either silver or black in color will have 2 rubber hoses hooked to it going down to metal tubes that hook into the exhaust.It will have a 3 wire connector with the color of the wires being BN/WH,BN/LG,OG. Disconnect one of the rubber hoses from the sensor and hook the vacuum/pressure gage into the hose.You should have less than 1 psi at idle,then press accel to wide open throttle and take a reading,it should be no higher than 3-4 psi. Anything more is an exhaust restriction.
