Are you sure that is what's happening? The fuse would go before the relay.

Relays don't just "burn out". They deteriorate and get weak over time. You can have contact or low voltage issues somewhere else effecting the relay but the problem is not likely the relay itself. You would need to run some voltage drop tests in the rest of the circuit.
