It's hard to take guesses at a problem like this - checking the sensor patterns with a scope is the preferred way to go and that's obviously not an option here. I would first check the connections to make sure they're clean and tight. Then I would check the cam/crank sync with a scan tool. Anything more than 6 degrees +/- and the sync signal needs to be reset by adjusting the distributor. If both these things check out ok, I would replace both sensors with Mopar parts (I've had too many repeat failures with aftermarket sensors to ever trust them again).
