Video Goes Away After 1-3 minutes

I have a Space Duel cabinet with a WG vector monitor. It has the LV2000 voltage mod and has been working well for quite a few years. Recently, though, it has stopped working properly. It sometimes shows proper video for about 1-3 or so minutes, after which the video cuts out like the monitor is not getting power.

The HV board with the LV2000 has the LEDs powered up. I suspect it's the flyback but do not otherwise know how to fix that. I also noticed a while (with I think a blue stripe) wire that is not connected to anything also on the HV board. I think it's been that way for quite some time and doesn't seem to affect anything though I am not sure as to what the wire does (or where it goes).

Anyone have any thoughts on what I should be doing? Since the tube is good I hesitate to swap it out for an LCD and use the VectorVGA stuff.

Thanks!

Tim
