I just started having this issue. Cold start-up is normal. The engine oil is warming as I slowly taxi out to the end our runway. Once oil temp is green, I do a mag check and the fuel pressure drops down into the yellow and I get a warning. Reduce throttle and the fuel pressure goes back up. On takeoff, I sometimes get an alarm. All other times, there's no indication of a problem.
The only difference is that I am still running 100LL in the tank, left over from my last trip. This only happens before the first flight and only when I advance the throttle to do the run up. Both pumps are running as I pulled the breaker to check and the pressure dropped, but not into the yellow at idle.
Any ideas?
