99 F250 diesel hesitates/dies intermittently
New member here, sorry in advance if I break any protocols. I have a 99 F250 diesel. Every so often I'll be driving down the road and the "water in fuel," "check engine," and "wait to start" lights all come on at the same time, stay on a few seconds while the engine falls to idle, and then all go off and the engine recovers power. Lately it happens more often, and sometimes the engine actually dies altogether. Several times it has happened when I was taking a turn at the bottom of a hill, but it has also happened driving straight ahead on the highway. May happen more often when it's wet outside.
I (very novice) thought it might be some clog in the fuel line, so I changed the filter and added diesel conditioner, but no change. The local dealership tells me they want to replace the CMP sensor ($350) and transmission range sensor ($450) for starters, and then they'll be able to tell more. It feels like they're just shooting in the dark. Do these proposed fixes fit the symptoms, and are those prices in the ballpark? It seems like I'm just a walking wallet to them.
Thanks in advance.
