Exclamation Ford 5.4 f150 just shuts itself down while driving.

I have a 97 ford f150 with the 5.4 engine and it runs great. It idles just fine runs just fine no check engine light or anything. However every once in a while the truck will just die while i am driving down the road. There is nothing that makes you think its going to do it. The truck just goes dead. Like the power is cut off from it. Its got 200000 miles on it. The battery is fine the altinater is fine and I just had the fuel filter changed. I dont know what is wrong with it. Does anyone have any ideals. Thanks

In addition to the engine dieing, what is the status of the rest of the electrical system (lights, heaters, radio, dash lights, etc) when the engine dies?

Need to determine if it's a complete loss of power for the vehicle or if it is limited to very specific circuits, ie, the engine or fuel pump, etc.

If your original owner's manual is missing, download a soft copy from under the PARTS AND SERVICE tab.

Does the motor start right back up again afterward? How does it die? Is it like turning off the key, or does it kinda sputter and wind down?

There could be something loose in the ignition in the steering column that is causing this problem. The other possibility is that the fuel pump for some reason loses power and quits temporairly.

Do you have a performace chip in the computer? When I first installed my chip I did not tape it into place - I was trying to make it easier to remove. I installed it when the truck was new. It would loosen up when the weather turned colder and the engine would die running doen the road - it did this every year for the first three years. I finally reinstalled it correctly by taping it in place and had no further issues.

dying 5.4

I have a 99 and it has done that since it had 40,000 miles on it nobody can tell me anything. It has done it 5 or 6 times since I bought it in 01. Gives you no warning when you get it to crank you have to sit there pushing the gas pedal to keep it running and if you let off it dies again. Finally after a little while it cranks right back up like nothing ever happened. The times it has happened to me I've been riding down the road and it just lost power that happened about 2 or 3 times. The other few times was after it had been sitting for several hours.

I agree with the ignition switch being the possible problem. I had a Thunderbird that would do this and this was the cause. Also make sure the cable from the battery to the fuse box is tight. Wiggle these things around.

Small World!! Mine did that after dropping my daughter off at school this morning - T he defroster was on and the radio was cranked, I didn't know it quit running until I tried to give the wheel a turn - then I looked at the instruments and couldn't believe it - 200k on my 98 4x4 -5.4L and it's never done this.
Last night I was working on it with the door open and pulled that 5 amp fuse because the door chime wouldn't quit frickin dingin, but I've done that before.
I t must have reset the computer - it was running and shifting like it was in learne mode.
The trucks not chipped, but I have heard of others in the past with chipped power strokes having that problem - truck would just quit at any speed.
I was doing about 25-30 mph when irt happened . It started right back up.

Check the crank position sensor plug and the cam position sensor plug for being locked on tight.
Either one come loose and open circuit, the truck stops in it's tracks.
These are the ignition reference points.
