Check engine light with loss of power

My situation this morning to work-check engine light comes on, power steering starts to go out and enginge starting to stall. Pulled over to the side of the highway and checked as much as I could in the dark. Engine oil, trans fluid, coolant, Power steering fluid, belt tension all good, no leaks. All connections that I could see or reach were intact. After checking all around and making some calls, decided to start it up-no problems, waited 5 mins to see if anything would come up-nothing, got to work, did another check, all is well. Forgot to see if any codes came up - check that later.
But does anyone have any idea what this may be-loose or faulty connector or something worse?

It sounds like you might have lost belt tension at some point so I suggest you check all the engine pulleys and make sure none of them are loose or wobbly.

CPS on the way out?

Thanks for pointing me in the right direction, did a search on CPS and alot of the posts exactly describes my symptoms.
