Hi, welcome to the forum, There are a number of reasons that the vehicle could be down on power so working thriugh them one at a time will help solve the problem as quickly as possible.

My initial suspect would be the MAF sensor. You could try unplugging the MAF sensor and seeing if you could repeat the problem you had .

 

You may get an early indication as the whether it is the Maf, if you unplug the MAF whilst the engine is running you should hear a change in the note of the engine, no change would suggest there might be a problem.

 

So start the engine up, unplug the MAF, listen for the change in note and then go for a drive to see if the symptoms replicates.
