sounds like you need to get the test light out.. if all guages went off at the same time, they are going to all be from the same source, so its just a matter of tracing it back until you find where the break in power is. having said that, it can be a difficult task, i had a similar issue and it ended up being a broken connection inside the fuse box that would sometimes work and sometimes not.
