Loss of power
 

Hey guys I have an 06 g35 sedan AT. The other day while I was driving I lost power twice for a few seconds and then it came back right after. I recently replaced the fuel pump about 2-3 months ago so I know it's not that but I noticed there were some cracks in the rubber coupler hose that is attached to the throttle body. I believe this is my issue but I'm not 100% sure. I have no cel, no vdc light, and everything else is nornal. Any suggestions?
