C P S problem???

On two occasions my truck would miss out of the blue,as if it cut off,the last time it ran a little rough and then returned to normal.I did not get cel either.My question is this the CPS?

It doesnt seem like the CPS, when you say cut off is it like you just turned the key off? or does it stumble a bit?

Yes, just as if you turned the key off and on as quick possible.A small hiccup and begins to purr as usual.Fresh oil and fuel filters,as I said it has happened twice and I thought it at first maybe the ignition switch could have been have way in the on and off position,but I can't duplicate it by hand so i ruled that out.The last time it did stumble a bit after the intial miss,but cleared with in seconds

Mine will do that if I goose it, lift and goose it again on old oil. I just change the oil and it goes away

I agree it must be an electrical but it it is alarming when it happens and always restarts without any problems.I did get a chance to clean and inspect engine and all wiring connections ,I noticed I have a black CPS and not the gray one I have read about on this forum,could it be my problem?I mean this truck with 97 k runs like a top,smooth idle,good response thru out.But any way I will replace the CPS with newer version and see what happens.Thanks for the help!!
