Funny light troubles

[maverick]

Hi All.
I own a M54 A2 and i seam to be having electrical problems with my light lately.

When driving here i the UK i always have the headlights on. When I'm testing my lights pre driving I have headlights on as well as indicators / hazard light while i do a walk around checking everything. If i leave them on for 3 min + i seam to be losing everything, then they come back on after a minute. What causing this? Any ideas???

Thanks

Anytime I have electrical troubles it is a bad ground connection.
