While accelerating the engine power will cut out for a moment and then kick back in. This only happens once in a while. Twice it has gone into what I assume is limp mode and one other time the engine shut off 10 or so seconds after.

Yep, this can be a limp mode or engine misfire issue, I would start by checking for codes which this guide can help on:

Next, I would do a full tune up with ignition coils and I would service the throttle body. Here are two guides to help and I have included instructions for your car in the images below:

2.4L engine typically uses NGK Laser Iridium Spark Plugs with the part number ILKR8E6 or Denso Iridium TT Spark Plugs with the part number IKH20TT.

Check out the images (below). Please let us know what happens.
