Just simply wont work

Question

Good afternoon everyone well this is my story, I was on the freeway exiting was no problem now as I'm traveling I noticed it was a slite uphill street so I went to give it a little more gas and realized it was paddle to the medal but was nowhere near the power,sound, or speed it should have been or at least near where I've seen it before at its best. Well half way up that slite hill she cuts off on me and was unable to start her up again for around three(3). Months of trying everything from spark plugs,coil pack,fuel pump,even replacing the whole timing chains and sprokets and tensinors, down to e.c.m,as well as anti theft system.once I got her started which up to date has now been over a year now she starts idles fine but put her in gear and idles almost to shuting down if she didn't shut down already and if I get her to stay on I again pedal to the medal and you might hit three(3) totwo(2) mph, I have way to much sentimental value for her for it was my 17yr old baby sisters first and only car, she passed on now and is the only thing I have left of her, it'll be highly appreciated if one of you guys can give me any clues or helpful advice to getting her running again thank you for your guys time and Godbless.

This sounds like a failed CKP (crankshaft position sensor) , this year make and model you just don't throw ECM at it, it has to be programmed for this vehicle. There been a lot of problem with the CKP failing due to its location and temperature that the engine would stall  low driving speed without warning , The ECM has to be programmed with the CKP update and perform the idle relearn.
