U0109 - Lost Communication with Fuel Pump Control Module

I noticed my car was running lean at WOT and saw this error. Last night I checked the 20 amp #35 fuse in the back and its good. The car runs and drives fine except at wot. I'll check power at the fuse today but wondering if there is something obvious that I am missing or should be checking.
