Hey guys I have an 06 g35 AT. The other day while I was driving I lost power for a second 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. Any suggestions?

 

Check for codes anyway, you may have one pending that hasn't turned on the SES light yet.
