engine cuts out
Started up my truck to go to work today. Got about 10mins down the road and then my engine just cut out. Pushed it into a parking lot got a ride and came back to it later and the truck started right up. Made it a ways and then the engine cut back out again. Thoughts?
My serpentine belt broke last week. Turned out to be a seized compressor that caused it to break. Ran the truck all weekend without any issues until today. Related?

Where is the fuel filter on a 1998 f150 4.2?
My truck is running rough and it is eiterh that or electrical short feels like a short to the fuel pump or something but it will idle fine just when you press the gas it sputters and dies then starts back up
Feels like its running out of gas but it also feels electrical

played around with it some tonight. Checked the fuel pump relays and fuses. All of those checked out fine. Tried putting some starter fluid past the air filter. Engine caught for a couple of seconds. So its not getting gas.
Now the question is clogged fuel filter or is my fuel pump bad? I'll start with the fuel filter unless anyone has some tips on how to tell if your fuel pump is shot. Any other possibilities I could be over looking?

So i disconnected the fuel line past the fuel tank turned the key to run and fuel pumped out. So the fuel pump is okay. Reconnected the line disconnected after the fuel filter and fuel pumped out. so its not a clogged filter. Disconnected the return line...no fuel pumped out. Going to try and replace the fuel pressure regulator tonight.

It's all fine to do this but you are not getting to the specific issue.
You may not see fuel out the return line on such a short pump run time.
When going to the run position on the ignition switch, the run time is only a second or so.
The 2 pipe closed system uses this short time to fill the fuel rails so the crank to fire is a very short inteval.
If you are experiencing an abrupt shut off of the motor, it is usually not fuel because there is still pressure in the rails that will bleed down and you should feel it as a slowing of the motor before it stops.
An abrupt shut down is electrical in nature such as ignition or a loss of DC power such that something stops working instantly or causes the igniton to shut off.
Cam position sensor: without it the fuel stops instantly because it controls injection sequence timing thus the injectors stop working elecrically..
Which you see when the problem happens dictates the direction you should look.
Have you double checked the crank sensor plug/ leads for being seated or damaged? An issue here will cause the problem of shutdown 'instantly'. No fuel, no igniton, no nothing at crank or run time..
.
Another way to catch the issue is using a mid range scanner to trap the fault while driving so you can see what the programs sees, then work from that point, on the hardware that may be causing the issue.
