Maybe something that runs off that fuse is beginning to short out?

if you have an after market amp wired into the ECU line, you have increased the current draw on that line. If the amp has a fault(it has blown its own fuse), then the overall current draw on the ecu line will be such that the fuse will be "stressed."

I can't imagine anyone running an amp on the wiring for the ECU, that's ludicrous.

it's not hooked up via the ecu wiring it's run direct 8g from battery to amp but the problem was partly due to the amp cable due to the short in the in line fuse holder but it's all good now :-)
