I've repaired dozens of Ford radios for this problem. The issue is the power supply module and broken solder connections. These are real frustrating to repair because there are so many places to look for bad connections, and when you think it's fixed, the problem acts up again about a week later. I always told used car dealers I was going to keep these radios for two weeks to run them on my test bench, or I'd send them a different radio.
You can go through the dealer and their two grossly over-priced repair centers. They will not fix your power supply board. They replace three boards that will develop the same problem in a few years. Yours has probably been repaired at least once already for this because no radio ever made it 17 years.
This applies to the cd / cassette combo radios. The cd radios and the cassette radios can develop intermittent display too but it's not as common.
