Randomly cutting out while driving

My truck just started doing this thing where it looses power for probably about a second and then just keeps going. Almost like I let off the gas but get right back on it, although I didn't move my foot. I am thinking it is the CPS but I am not sure, I do know that we never got the new one installed (grey I think) and are still using the old one that the dealer put in the last time it went out.

Any help is appreciated.

Thanks

I'd be thinking TPS...

"Almost like I let off the gas" could be exactly what the PCM sees. It's a common issue to have that potentiometer crap-out. It can also be tied to the OD sw wiring chafing under the column and drawing the circuit down (might be a good place to check anyway, it too is a common problem)

I'll try the CPS and if that doesn't fix it I will move on to this. From what I have read, however, it seems that what it is because it shudders and has shut off at random times but started right back up.

Yea but, here's what the typical Bad CPS does...

As that sensor takes-in engine heat things go wrong (not sure exactly what that is ) and once it stops working it doesn't work again until it cools off a significant amount. This usually means 10-30mins.

I'm not saying it can't be the CPS, just that the old Black ones were Much more susceptible to this than the Grey ones are and if it just stumbles momentarily or restarts immediately it sounds less likely to me.

Well the black one is the one that is in the engine at the current moment. Just picked up two grey ones from the Ford dealership.
