My jeep starts fine, no problem. turn it off come back in less then 20 mts. then it stalls, engine lite on, why?
All stalls end in CEL check engine light on. that is normal
but CEL glow. when engine running , means you had a failure, and it stored DTC error codes, so scan it.
lots of causes. huge list.
get a tune up , tops list.
SCAN it to be sure all sensors work. running.
all fuses in car good.
by stalls , i assume the engine stalls and engine RPM is 0 RPM.
the stall cause the whole dash to light up, all the warning lamps come
on (self test) oil , charge , CEL. come on.
what is important is the stall and the cause.
i will tell you the 3 ways.
lost electrical power to engine EFI system (seems not)
bad engine, (lost compression hot)?
bad spark , spark died.?
bad fueling, lost all fueling (starves and stalls or floods and misfires horribly and stalls (black spark plug tips are big time clue)
if non eof the rings a bell.?
get the car serviced.
this car is newer nicer car, you (we) can scan and drive and log data.
allowing faster easy diagnosis.

Take the air inlet hose off where it enters the throttle body and take a look at the throttle plates. It is likely that they’re dirty and have a build-up of carbon deposits. That is the most common cause for stalling that we see in the shop for your vehicle. Sometimes all it takes is a good cleaning to cure the stalling problem. There is an idle speed setting on your Jeep, but to check and/or perform this service step requires the use of a computer scan tool for your vehicle. If the cleaning doesn’t help ask a repair facility to check and reset, if needed, the minimum idle speed on your Jeep.
Thnx.

check your transmission fluid,the motor will stall when fluid is low
SOURCE: check engine lite is on. how can I turn it off?
You will need an OBD (onboard diagnostics) handset to read and or reset the codes. It would be good to know why the lamp came on to aviod and break downs possible in your future. They are available in any automotive store or even the auto section of many major Dept. stores. they generally include a code book or sheet to decode the reason for the light coming on. you may not be able to reset the light with out resolving the issue causing it to come on.

P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

It could be air fuel mixture. See if applying cleaning solution like tuner cleaner in the intake particularly on the MAF sensor will help. Check also for loose connections from the air filter down to the intake manifold. Check for loose connections, cracks or gaps where air may pass. This would skew measurements taken by the sensor. Check loose vacuum lines or cracks or loose vacuum lines.
Check also the fuel filter if it needs cleaning. The problem may also be due to inconsistent fuel delivery due to a bad pump or relay.
Other items that may cause this is a dirty or faulty EGR valve or injectors that need cleaning.
If you can have a scanner connected to the diagnostic port it would be great. Even if the check engine light does not turn on there could be errors in the ECU saved which may help diagnose the problem. Some shops like autozone would let customers borrow this for free.
