Momentary shut off...CPS ??
This morning I was driving my whopping 2.7 miles to work and twice the truck dies for a split second and then takes off like nothing happened. It was like she just tripped but she don't have legs.
My first thought was CPS. Any other suggestions?
I just replaced the CPS with one of the expensive ones from O'Reilly's right before the prices dropped to 20 bucks. (just my luck) I still have the old one but it did the same thing before I changed it but more often. Is it possible for the CPS to only last 1 year...(stupid question I know).
Anyway it has a lifetime warranty on it so maybe I will swap it out and then put the other bad one in and take it to the dealer for my recall.
BTW it was colder this morning than it has been in awhile 29 degrees.

sorry, just read the rest of the post about swapping before the recall.
I wouldn't waste time troubleshooting with the history of these things, almost guarantee to be the sensor. Seen them last for 200k without a problem and seen new ones die with less than 6 months/5k on them. Hopefully the new ones are more reliable. Any had any trouble with the new ones that you guys know of?

Thanx guys. I pretty much figured that is what it may be but I just wanted to bounce it off some of you guys.
Rick you said ICP huh? I will look there too. Doesn't hurt to clean contacts now and then.

This I saved from a poster on TDS ..
OK, here's the long version of my deal--still not 100% sure what's going on, but yesterday on the way home from work--minding my own business doing about 50 mph--truck just shuts off. I've had this sort of thing happen before about 40k miles ago, so I'm thinking CPS--when I didn't get tach movement after trying to restart it I just knew it was CPS.
Last night while the truck slept in the spot I rolled into, I got on here to find out that Ford now sells them for a reasonable price--great news!
So this morning I hop on the motocycle and get two CPSs (I know should've did that last time). Replaced it, she fired right up, and after loading my motorcycle in the back I took off to work--problem solved.....or so I thought.
About the time I roll in the parking lot at work--dead again! Same symptoms. No tach needle--and this time I noticed my WTS light did not come on (could have been true yesterday--was too focused on the tach needle to notice).
At quitting time, I crawl under the truck with the new spare CPS and this time it does not fix it! Still no start. I started checking fuses and all were good. Then I get to the relays. There are three in a row with identical part numbers 1)PCM power relay 2)blower motor relay, and 3)Injector Driver Module Power Relay--just guessing, but I get lucky on the first try by switching the PCM and blower motor relays--dang thing fired right up! Checked the blower and it sure enough it doesn't work. So now I'm heading to the local auto chain store to get another relay--all the sudden I notice the blower starts working! Guess what I was experiencing was an intermittent bad relay.
Now for my questions:
Would anything have caused this relay to go bad--in other words is it merely a symptom of another problem? Truck is 2000 F350 with only 94k miles--is a bad relay normal?

Like Bill said ,,many don't need them ,,they just need to remove & install the wiring again ,,,cleans the contacts ..
Like most that have charging problems ,,get a new alt ,,when installing ,,the belt gets tightned properly
