I sounds like heat might be a factor.
You can get a can of circuit cooler and spray the ic and see if it works longer.
You can test the IC6100 by looking at the input and output. If the input voltage is in specs and the output falls then IC6100 may be at fault. If you have an oscilloscope with two probes you can see it in real time.
You can get a similar action with bad electrolytic capacitors which will eventually fail. You can replace the electrolytic capacitors with low ESR high temperature one.
