could be a number of things.... check to see if you need your injectors cleaned.. might not be gettign enough fuel to the engine. depending on what mods you have you might need other things such as a fuel pump.. What mods are you running right now?

I had random fuel cuts that gradually got worse.
Check out this short (fuzzy) video clip.

link to video

Each rev up was at WOT.
If you look close, you can see the boost gauge go to 0.
The fuel cuts were caused by a worn out TPS.
The TPS idle setting was perfect, but the resistor was badly worn at part throttle, so the ECU was getting bad readings & going nuts.
