OK, it's cold outside negative numbers, and after 45 miles tonight on the highway I lost pressure again. So I don't know if it's the distance or the temp but something is triggering it. Poured in about 1/2 a queart of PS and half of 2 stroke tonight, see if the PS cleans anything out. Guess the next step, when I can feel my fingers out there is to drop the tank.
