Sounds like your ignition module it is common on fords to do this when its cool it will start and run fine but once it heats up the truck dies until you let it cool down again and then your up and running till it heats up again. Some modules are mounted on the fender others are mounted with the distributor have it checked and let me know how it went.

Engine shuts off after driving 45 min when parking in reverse.But 15 min before this engine and slippery road icon comes on.2 hrs later car starts and drives normal then shuts off again 45 min later.

most commonly found problem relates to an electronic component heating up and shutting down. Have you checked to confirm there is fuel pressure when the vehicle shuts off. Is the check engine light on. Have you checked codes ? I suggest hooking up a fuel pressure gauge and letting vehicle run till it shuts off while monitoring the fuel pressure. If you loose fuel pressure, next step is to confirm there power going to the pump, if there is power going to the pump with no fuel pressure replace pump. Another suggestion would be to check for spark when vehicle stops running to eliminate an ignition problem. good luck

Have a 2005 f150 4.6 that stalls can it be the fuel pump is weak

Could be a fuel pressure regulator not working. Thus ecu complaining about fuel Pressure. probably not enough because the regulator is worn and leaking down so will not maintain the proper pressure. You will need to google the make model and fuel pressure regulator to find it's location or library and repair manual. Otherwise, you need to measure the pressure and find the spec for the required fuel pressure. Probably somewhere around 120PSI

Fuel engine stops then start up in 1 min

You probably have an electronic ignition system to go with those fuel injectors. It sounds like it runs just long enough to empty the fuel out of the injectors, which means there might be a vacuum problem. I'm a carburetor person myself. Are you sure it sound like it NEEDS gas or could it be flooding?

Fuel pressure intermittently drops causing sputter and die.

check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

Runs fine for a few

it might be the fuel pressure regulator, i have a similar problem with my 95 302. but mine just dies but starts right back up. i was told fuel may be evaporating out of the fuel lines, when it doesnt start the first try i pump the gas pedal 2-3 times and it starts right up.
