Was out for a nice back road drive in Chester, my 70 911S with MFI. Was running great for about an hour at normal operating temps, and then it started missing at full throttle. The missing got progressively worse to the point I could barely keep my speed up. It finally died, and would not start. Fortunately I had made it most of the way home and with a short tow, got it back to the house. Next day it started right up and seemed to run fine.

I suspect I have crud in my tank that covered the inlet screen, and it died from fuel starvation. After it sat with no suction on the screen, the crud fell off, and it was able to run.

Any other suggestions or ideas before I drain the full tank and pull the screen out? Tank is 3/4 full and I HATE draining out that much gas!
