CPS sensor or pigtail can act like that prior to total failure

Just change the CPS, put the old one in your glovebox as a spare. If it fixes your problem, the installation time on the CPS is pretty easy and you'll feel like a million bucks. If it doesn't fix it, you'll be $30 poorer but have a spare for when the new one craps out down the road.
