Default P0620 code help please

Hi,
Very occasionally when the fuel warning alarm goes off for low fuel, the engine management light comes on... It's showing as code p0620 - generator circuit malfunction. Seems strange that it only happens then and only very occasionally (twice in 2 months) if I stop the car and take the keys out for about a minute, then restart... Problem solved... No warning light but its bugging me now... I like things to be right!

I'm a complete novice when it comes to electronic gadgetry, but happy to have a go. Any advice and comments great fully received... What should I check first?
Thanks

Toby,

Tried a search and can find no correlation why the "generator" fault light would come on when your low in fuel but allow me to pass on some information I received a long time ago when we had a mechanic (with his own shop) as a member of this forum.

The fuel pump is in the bottom of the gas tank. The gas itself not only cools the pump but also lubricates it. One too many times of letting the fuel drop down to where the warning light comes on can severely damage (burn out) that pump. A new pump is around $300 plus the labor to replace it not to mention that if it does burn out, it will be like your battery going dead, it'll never happen at a good time and will leave you stranded when it does.
