Does your GPS have a display page indicating satellites received and their signal strengths? You might try changing the antenna and/or the antenna cable in a temporary rig. My oldest GPS is a wonderful anxiety tester, it starts to loose satellites the moment it is really needed. The other two are OK. However, I know its problem is a poor antenna cable, coax doesn't seem to live long on my boat, it doesn't like being sea washed frequently and salt air soaked, I guess.
