If you have more than 1.5mil sP total in your account (spread across on-hand sP, deposited sP, and sP in shop tills) you will be unable to do Sarah's Quests. If your total drops below that you will be able to do her quests until you reach that amount again.

i have over 1.5 million for a long time ago and i always can do her quests

Huh. I did a bit more digging and it looks like new accounts may have the sP limitations waived for a time, but I can't find confirmation on just what the time limit is on the waiver. Your account may be too old to qualify for the waiver now.

For future reference if you still want to do her quests, the sP on hand amount does not include anything in your shop till. It does count what is in your bank, however.
That's why I tend to hoard what's in my shop till until I'm ready to make some big purchases, and I plan my questing so that I can do both Sarah's and Sagittarius' on the same day.
For example, if I start out with a low amount of sP, I'll do Sarah's quests first, then Shinwa, then Wizard, then everyone else (doesn't matter what order everyone else is in, although depending on how low my sP is I might need to wait to do Saggy). I usually end up with anywhere between 3-5 million.
Then if I don't spend anything that day, the next day I start with Shinwa, then the Wizard, then Saggitarius. Then I try to coordinate it with buying a big-ticket item that I want (gender berry, 1 week gold account medal, 100 CSC gift card, etc.) with how much I have on hand so that I can get below 1.5 million again and do Sarah's.
Anyway, that's my method. I don't always get to Sarah's if I'm saving up for something in particular, but I do on most days. You don't have to do it my way, but it might give you an idea. :)
