What GPS are you using? The original HaiCom 204III? Believe it or not I have had one of mine do that very same thing and the issue was a bad HaiCom. Try changing to a BR355 or another Haicom. I have a boatload of them I am more than willing to part with for a song., The other cause for that phenomena is static discharge. Does your unit have the grounding 'spring' I'll call it, added that grounds the PCB to the chassis? And if it has it, does it in fact make contact with the case. They can become bent so they are non-functional with a lot use. If it doesn't have one you can easily fab a makeshift case ground of some sort.
