Which specific fuse is blowing? Apart from the gauges, anything else not working?

Do you mean the one marked "Gauge" in the diagram?

Affirmative. A diagram I had seen before called it panel fuse. Sorry.

I just want to be sure so that we don't go barking up the wrong tree. It is also labelled panle fuse.

This fuse is for A/C switch, ashtray illumination, blower witch, clock, lighter illumnations, combination meter, glove box light, hazard switch, O/D main switch, radio and player, rear window defogger switch and rheostat.

There is a short in one of the components or their wiring circuit and this is not going to be easy to handle.

Since shorting only occurs after some time, this could mean a bare wire somewhere is coming into contact with body grounding points and vibrations would result in the circuit getting grounded. Check the wireharness for the dash panel and look out for clamped or bare wireharness.

There is a panel fuse of 7.5a but gauge fuse 10a is one that is blowing. Clock, radio, hazard lights, etc. All working with blown gauge fuse.

Just discovered that blown gauge fuse also causes power windows/door locks to not function.

Yup, that is because the integration relay is not being powered.
