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!

make sure your hose from the idle air control (IAC) valve, on the throttle intake, is not leaking. i just went through this myself. it is a small hose that connects to a nipple directly next to the thermostat housing, and the other end goes to the nipple of the IAC. you may not even notice a leak. if this doesnt fix it, the IAC is probably shot. also, make sure your coolant is topped off with the heater on before you do ANY of this. toyotas are seriously "coolant-dependent" trucks, and sometimes that is all that is needed. hope this helps

the way you are describing it it is sounding like the fuel filter is started to clog and might need to be replaced.
you may also want to look into a tune up i.e spark plugs and wires and rotor cap and air filter ect ect ok?

When your vehicles stalls, check to see if you also loose other indicators as well. Check your indicator lamps. If you have lost all power, this may indicate you have loose or corroded connections from your battery. Im sure you checked your battery already. However, a common mistake people only check the voltage. You also need to check to ensure your battery has a proper/solid ground to chassis. Sometimes these come loose and/or corroded. Clean your battery terminals and battery cables really good. They all should be shiny. Tighten them firmly when you reinstall. Try and start again. Sound to easy, but it has solved many issues with the problem your having. Hope this helps.
