Got a shower upstairs that works fine for about 5 minutes, then the
water gets really hot, then colder and so on. This is happening
without anyone in the house using anything. House was built in the
late 70's early 80's I guess with a newer water heater and copper
piping. Any ideas?

Gas? Electric? Heater

Run water and feel the outlet pipe at the heater.
Does the temp vary (a lot)?

Does the shower control have scald-gard or similar temp control?

Jim

Gas heater. No, no scald guard.

Dip tube fell off?
