Fish Finder Power Up Issue

[spicolly]

My FF (Lowrance Elite 4X CHIRP) is behaving weird. I bought it new this last Spring and recently have ran into an issue.

During my last 3 trips, it has not powered on while launching. I trying powering it on while paddling out and around the water. Nada. Then, intermittently and for no reason, I'll try to power it on about an hour to an hour & half into the water and BAM - it powers up and works as expected. It's very odd & FRUSTRATING! I've checked the wires and voltage...all appears fine. Bad unit? Fuse? Any thoughts?

Thx!
