While driving the engine chokes, hesitates and then shuts off

This project cars about to wear me out!

This problem has happened twice. Most recent was just before dusk about a quarter mile away from my house I’m old and did not want to walk home but I decided I would.

It was running fine I had just replaced the fuel sensor approximately two weeks ago and a month before that I had the air sensors? There’s two of them I think that’s what they’re called you reach them from the car and they are on opposite sides of the engine if I remember correctly when I got underneath the hoist. Well, it did the sputtering hesitation thing again the other day so I just pulled over to a side street called some help and then it started back up about 20 minutes later my friend followed be home. I drive children around in this car cannot have it doing this. The shade tree mechanic that’s working on it says that the crankshaft position sensor is probably out. Can you just slap a new one back on or does something need to be checked to be lined back up since the word position is on this part? Anybody want to buy a 2005 PT cruiser convertible?
