94.5 7.3 5sp: Sudden death (engine cut off) please help

Hi,

My truck died today, suddenly cut off, definitely would seem to be some sort of electrical issue as there was no sputtering or fuel type symptoms.

Here is some background: recently spent a ton (relatively speaking) of money having 4 injectors replaced along with new IPR. Also had complete rebuild of fuel bowl and related sensors, fuel line, etc done at that time.

About a year ago I had valve gaskets replaced as well as related wiring harnesses.

Also, fyi, couple years ago my CPS started to go bad and was replaced with a new sensor. So I am familiar with that problem - also kept the old one in my truck in case new one ever failed i'd have spare to limp home on.

Also have two new batteries and full charge - so when I tried to start truck back up, starter was spinning at full/normal speed. Although starter is turning over fine, there is NO pop, NO smoke, Nothing.

Up until it died (about 2 miles from home) today, truck had been running fine.

What I tried so far: not much yet, but I did swap out the CPS to the old one with no change in results before having truck towed home.

Looking for advice? Just looking for some tips and trouble shooting advice before biting the bullet and most likely having to have this towed to a shop.

Please help!

* Are you getting the WTS light?
* Is the tach moving when you crank it?
* When it died, if you can remember, did the tach immediately drop to zero, or did it continue to read as the truck coasted down the road?

Thank you!

Typing on phone so will keep it short. Thanks for all replies and special thanks to Dan for taking his time with me on the phone.

Yes it was shorted fuel heater (which did blow a fuse under hood).

Good lesson learned, if you have something similar happen, try to remember to first check (turn key off then on) for WTS light. If no WTS light, move to fuse box under hood. Then check items on that circuit, fuel heater is likely culprit.

Lastly, I learned again today that my stand pipe is 2 sizes larger than noted in most write-ups (and remember it is reverse threaded)
