Hesitation during WOT at 7k RPM - Fault code 2788

[jvictormp]

Hi guys

I was going the other day to a trackday, and during the trip to there, with WOT leaving the toll, 3rd gear, 7k RPM, there showed up a fault in the dash: fuel pump fail, reduced power, service engine soon.

Switched off the engine, started again, no faults.

Went to the next gas station, fuel tank was like 40% full, and I refilled it up. Premium gasoline as always.

During trackday, WOT all the time, 8300RPM, no problems.

INPA showed the fault code 2788. (the first two are not related, and the last one is the emergency program)

What you guys think? Should I replace the low fuel pressure sensor?
