Over Frustrated

I've been Having this problem where my 98 wrangler 2.5 won't start up again after I drive her around and park. When I attempt to start it up after the motor is Hot she will either stumble like gas has turned to vapor or won't start at all. I took the Temperature Sending Unit Sensor plug off and it started Right up- or if I pour a little bit of water on the TSUSensor she'll start right up. Auto parts store say I have the correct Sending Unit on that motor but then why is acting like it's over heating and won't start? Any Expertise out there ever hear of this dilemma?

By removing the temp sender to start it you are faking out the ecu so it starts. Got to figure out what is sending bad data or needs to be replaced could take a little research.

Does it throw any codes???

Its a 98 with round headlights so its a TJ. I run a 2.5L 89YJ. If I find something I'll let you know.
