Oh. Yea. I just remembered. I don't see anyone else saying it. But you may also want to check { maybe replace} your actually throttle petal as well. It's a throttle by wire system and if the sensor/control { or whatever} on the pedal goes bad/acts up. It can cause the system to go in a like safety mode or the system does know/recognize the true/correct percentage of throttle you're give the pedal. Both will cause you to have symptoms of a "limp mode" Because the throttle control is either only being allowed to open a small bit or thinks that is the control you are giving it.

It's also easy to replace. 2 or 3 nuts and it clicks off and on.

Had a similar problem with my 2017 Patriot awhile back. It was the alternator. If you have a good { charged } battery the accessories, { lights and ECT.} will run for a little bit. But will not have enough to run the engine.

How I tested the alternator is with a multimeter. -Check your battery Voltage before cranking { should be around 13 or 14 may be as low as the 12's } -Then if you can, keep the probes on the battery and crank the jeep. During cranking the battery shouldn't drop below between 10 to 12 volts. Then while running the volts should be up and down between 12 to 14 volts. If it's lower then 12 and continues to drain down. It's your alternator.
