Please help with Leprechauns

As the title says I believe they’re insight my engine. When they dance my Jepp stalls or starts coughing a lot . 160.000 km , Grand Cherokee Limited 2007 Hemi V8 5.7 L
I figured that usually there is a link between the leprechauns dancing and this magic instrument that makes them hiding away for a few kilometers. If I am shaking it and knock it car will run well.
What exactly is this ? it’s located close to the battery , there’s two thin pipes coming into it one from throttle and one it goes probably to the tank. Is this a sensor, a valve?
Thanks

Did you disconnect the plug and clean the pins and holes they go in? Many times corrosion gets on the pins and makes a dirty contact. Do you have electrical power when it stalls?
You might also want to check your fuel filter. With 160k it could easily be plugged and would easily stall the engine.
It looks like a pressure sensor of some kind. Possibly for the fuel flow if one comes from the tank.
Not familiar with the Hemi. But contacts and fuel flow are common to all motors..
Hope this helps.
