engine died at highway speed?????

[TBM_F350]

On my way home from work this afternoon i was crusing along at at highway speed 65-70 mph and my truck cut out. It did not completely die, but the instrument cluster flashed on and the engine cut out (i could hear that) and then it "restarted" and i kept going. It did this 2 times in a matter of 3-4 minutes. I drove for another 15 minutes to get home and it ran the rest of the way home. WTF??? Any ideas? From what i was told the previous owner had the CPS replaced about 10-20k ago.

Thanks,
Tim

Any codes?

[TBM_F350]

Nope, no code reader yet. Hopefully santa will bring me the AutoEnginuity code reader i've been asking for.

Interested as mine did this as well.

the problem is the CPS change this sensor and that should solve your problem.

Change the CPS sensor. Mine did the same thing both times the sensor died.

[TBM_F350]

I ended up changing the CPS and it still died on me. I removed the hypermax chip and the problem hasnt happened since. Is there anyway to test a chip to see if it's bad? The terminals didnt seem too bad like there was a lot of corrosion or anything like that.

I had a hypermax chip for several years with no problems. If the conformal coating on the board wasn't cleaned off good, this could have caused an intermittent connection. On the other hand, it could be a chip going bad. Not sure if there's a good way to check it though.

ya mine kept dieing,,, id reach undernieth and wiggled the cps wires and it'd fire back up and run fora while then die again... so i figured it was the connector, with the 3 wires comming out. so i called international and they had a conector in stock-i put it on.. now the truck will not start at all... what so ever. the tack wont show any rpms. I have a hard time believing it is the cps because ford recalled it and replaced it about 20k or less ago... ... not sure what to do... cant afford to take it to a tech.

Oregon stroker, are you sure you got the connections good? Also did you get any wires crossed? (Just asking the obvious questions first)
Those CPS' that Ford was using on the recall were from another supplier I believe, They were MOST CERTAINLY cheaper priced, either a HUGE markup on them, and tons of profit. Or they found another supplier. And there have been many instances of them "Going bad" again, quickly. It would be worth another 25.00 to try one IMHO...
