When I start the engine, it idles okay and seems to be running fine, but then when I rev the motor there seems to be a half second or one second delay to when the engine responds. Then, when I put it in Drive to take off it just Shuts off. And this does this over and over. I've replaced the throttle positioning sensor the alternator is tested good I removed the throttle body cleaned it thoroughly looked at all filters all fluids are fine, but I'm baffled.

Does it happen in reverse as well? If so, you have a torque converter that has some part or the TCC solenoid is stuck on, here is the location for the solenoid so you can swap it out and hope that fixes the problem or the transmission will need to come out and torque converter replaced. Also, we should run the codes as well.
