Sounds like a fuel pump, but start with the filter.

SOURCE: truck starts, dies. truck runs good some days,bad the next

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: E85 fuel in a regular gas tank

Siphon out as much of the E85 as you can and fill the tank with good gasoline and drive it like you stole it for a while. You can't drain a tank without removing it and the fuel filter isn't going to catch anything in the E85. This is what I would do anyway.

1. IAR Valve
2. Fuel filter
3. Fuel preasure regulater
4. Slow to Go FUEL PUMP

SOURCE: Ford F-150 starting problem

replace the fuel regulator,its about a $50.00 part and takes about 15 minutes to change,but first relieve the fuel pressure and you can do it in a couple of ways,hitting the fuel pump shut off swith(inertia switch)until the red button pops up,but remember to reset it when done,located either behind the passengers side kick panel or under the carpet in the middle under the dash then start it to run it out of gas which there will still be a little bit in the lines,...or drain it at the valve to check for pressure it looks like a valve stem for a tire.
