This could be the camshaft sensor, the engine computer, or something else. If it is the computer, newer ones (probably starting in 1996?) you can kind of fix solder joints on and it might fix it, older ones have the main board covered in potting compound and really can't be worked on. Either way you can try to outright replace it. But it might be easier to check the camshaft sensor first. I'm not an expert I will admit, and my Jeep still seems to have issues after replacing both, but these are solutions that have worked for other people.
