That is an issue with your phone itself, not the app. If Map My Run loses GPS, Strava will too.
I don't use the Strava app, because it doesn't exist for my Windows Phone, but I do use the service and sync the actual app I use on the phone to it. I like it for YTD mileage and general statistics to give me an idea how I am progressing in my riding overall.
