Those couple seconds before it switches to FM, does it play the preview channel or is there no sound at all? There may be an issue internally with the radio or the Satellite antenna. I'd lean towards an issue internally with the radio though. You may have to swap it out with either a new aftermarket head unit or a used factory head unit.

When I set it to satellite a couple seconds later it switches to fm  all by itself,only does this when set to satellite 

When you say switching, do you mean when you select Satellite, it immediately goes back to FM? Or does it switch between the two on its own? Also, does it switch back to FM if you select AM or another source?

My dealer did mine a few years ago, as per the TSB, no issues so far. Just FYI that the TSB fix is holding.

I may or may not be able to provide any help for you, but no one can unless you provide a bit more information.  Year, trim, is this a new to you car, have you done any work on it that may have affected the radio, etc.  Welcome to the forum.

Thanks for those links @enigma-2   This has been bugging me for a long time and I've seen two DIY methods that I'm considering.   The one in the attached PDF uses 3/4" pieces of coolant hose with hose clamps, but I'm leaning towards the sway bar clamps.   Just not sure what size sway bar clamps to get, 3/4" or 7/8"  - might get both sizes off Amazon.   Two-Piece Clamping Collar, Carbon Steel with Black Oxide Plating, 7/8" Bore Size, Set Screw       TSB 18-2361.pdf

@smcmurrayNice to hear that you solved the issue. how much you paid for new fuel pump inlcuding labour.  The issue persisit on my ford edge. Should I replace with new fuel pump to fix the issue?

Sure sounds like good old fashion vapor lock. I also wonder if the fuel strainer, if it had one, was plugged up or restricted. With low flow, a vapor lock condition, it would take some time to purge the fuel system of vapor to start injecting liquid fuel.
