1st Rebuild with some interesting issues

I'm back again guys. So, i replaced the timing pulley and got the car timed perfectly. So i drove the car about 200miles so far and ran into a problem. Literally, once i hit 200miles i lost all engine power. I can start the car and it idles no problem. With no load on the engine, i can rev it (only went to 5K, I don't really want to rev it any more than that). Once i put it in gear and try to drive it it has no power, i can get it moving but as if it has a 50hp eninge in it. So i checked the obvious, TPS is OK, MAF is OK, i have a spark on all plugs. I don't think it's a fuel issue since i can rev it with no hesitations when the engine has no load. I'm not sure how i would even check if it was a fuel issue. The only thing i can think of is a vacuum leak when the engine is torqued when trying to move. I need to get out there with a propane source to sniff that out too. Do you guys have any other ideas as to what might be wrong. I'm at a loss at the moment and not sure how else to trouble shoot. Thanks in advance.

So yea, i have taken it easy on break in. Usually going to about 4K max some times hitting 5K. As for limp mode, I did some research and found that S4s don't have that. I did read that the O2 could affect the acceleration. So maybe i will try changing that out and seeing what happens.
Any way, keep the info coming at me. Thanks!
