Help! Really unusual engine or ecu problem.

smoothtransit

about 2 months ago, I was driving and I was climbing rpm to around 3500, my car began to lock up and cut power then come back. This occurred through various gears, so I parked my car and left it for the night. The next morning there was no problem. Then last night, after washing my car, I went to go drive it and the same exact thing began to occur, considering how dangerous it is for the car to lock up in the middle of driving randomly, i pulled over and restarted the car. The problem however continued. I managed to get it home and upon starting it this morning I havent experienced the problem (my morning commute is short however).

This issue is seriously sketching me out and i have found limited info on the issue on the web (granted its really hard to describe). Anyone have any ideas/suggestions? It strikes me as a serious issue. The car is a 6spd,sport pack,2009 with 50k miles on it

Also, I think that its unusual that the problem went dormant for 2 months then came back.

I did find this thread: limp mode for no reason at all? but it doesnt seem like there is a proper solution.
