Intermittent Fuel Pump

Thanks Dillen. I'll mention this to Glenn before I go there. Maybe he has a seal kit or a used CP1 ready to go. Where is the regulator, on the end of the rail?

Not on mine Francesco. It was changed just before I bought it and I changed it again today.

P0087 showed up before the filter change? Or after? I had the exact same situation -- stalled under load, hustling up a steep bridge ramp, stalled a couple more times after I turned around to get to a clear place to park, then set the P0087 code. I had changed the filter perhaps two months before, less than 5000 km. when I removed it, it appeared to be full of crud. I put a new one in and the code never returned.

It happened again today about 30km after I changed the filter. The previous owner had the filter changed at the dealer a couple of weeks before I bought the car. I need to drive another one to compare with mine. My gut feeling is my power is good on the first half of the throttle but is a little lacking at full throttle. Tolsen has said something about the CP1 reducing output at low speed. I wonder if mine is like that all the time.

The follow up to my issues with the P00087 code from last year.  It appears my problem only happens on warm days 27c or more so we had quite a few this year.  A month or so I had Glenn do a service and he installed his intercooler scoop and also noticed the intercooler fan was not working.  I ordered and installed the Spal fan he uses and my intake air temperature has dropped by at least 25c and have had it quit only once in the last month.  It quit about six times on the way to Glenn's before the repair.  When I get brave I will attempt the seal kit for the high pressure pump.

Sorry just realized I never posted the resolution to my problem.  New seals in the high pressure pump worked for me.  Thanks dmoonen you were right on.
