This is probably because you're using the 'multistroke' brush. This is - by design - a brush that only lasts for a single frame, since it was primarily intended for 'dust busting' in the past.
If you want to have strokes with longer duration you have to select the normal 'stroke' or any other option. If this doesn't help, than something else might be the culprit.
