Why did my 2011 Jeep Liberty 4x4 3.7 L V6 suddenly stop running at 128K mi?

What is your question?

This problem has never occurred. No indicator lights, mechanics diagnostics, car inspections have reported an issue related to this anomaly. I am very meticulous about the maintenance of my vehicle. On 6/21/19, in the middle of the highway, my jeep began to sputter, shook, & stopped running. Over 2 months later, 5 mechanics, including a certified Jeep-Fiat dealer, $4300 including tow truck fees, I still have the mystery of a Liberty that refuses to start. When you turn the key, there is no click or anything. The hvac, radio, & dashboard turn on but the engine does not ignite. The first repair was the fuel pump. $100 diagnostic from the dealer, then $854 to replace the starter and battery, which is outrageous. Turned out the engine seized. I replaced the motor with a used 96K mi & Autozone installed a new battery. I researched safety recalls & had the TIPM rebuilt, found a shortage in the ignition wiring and replaced the ignition switch. As of 8/23/19 the jeep still won't start.

What makes this problem better or worse?

Jump start from a bigger engine.
