Loss of power

About a month ago my car lost power on the motorway from around 70 mph down to around 25 mph. I had to stop and restart again and that worked. But recently it has started happening more often. The power just drops, I put it in second gear put my foot too the floor and after about ten to fifteen seconds the power comes right back up.

Any ideas?
Thanks

Hello,

This could be a problem with your Powertrain Control Module(PCM) AKA,"computer" or your Computer Area Network (CAN) system. I have included a couple of links down below.

Just to add also, has the check engine light come as well? If it has can you have the codes retrieved. If you have codes indicating a behavior fault then a software update for the ECM should take care of the issue you have.
