Well, a bit not clear what exactly had happened.
Did you lay down before it? Sit down tucking your leg under the body? if so it might be just a sleeping leg, it happens.
when you started to walk, you were able to walk normally? Did you have any visible foot drop (in other words, was your foot dragging when walking or not?). Did you limp? Was this feeling temporary?
Practically good rule of thumb invented by ALS people is FAILING NOT FEELING, in other words, paralysed muscle fails to fucntion, in other cases (like in BFS) person just feels like muscle is going to give out. Which seem to be your case.
If you search using 'give out' as a keywords, you will see that many fellows report that feeling of being weak and 'ready to give out', however they seldom report that in a words like you did ('like it was not there'), that is why I asked several extra questions in the beginning.
Usually in our case it is a sensory feeling (paresthesia), or error in the central processing of the signals coming from your leg.
If you still can walk even having your leg numb or 'absent', it means that all systems in your body do their work just the 'central processor' is a bit out of order, which happens in the beginning of BFS quite often.
but paresthesias itself could be a sign of nerve pinchment, circulatory trouble or local neuropathy, and if they would be persistent, it would be worth to bring them todoctor of course.
