I've been getting this code for some time now. High pressure fuel rail. Van ran fine so I would just reset the check engine light and it would go a month before I got the code again. Yesterday morning the light came on again. On my drive home, about 2 hours, the vehicle lost power momentarily, maybe a second or so, and then ran fine for a while. This happened 4 times, twice while pulling away from a stop, twice while driving at highway speed. Are these things related? Is the power loss a fuel pump on the way out? Van has 165,000 kilometers, I've done plugs and fuel filter recently.

Thanks,
