TJ98 Electrical Fault

Lo Jeeps,

Trying to get a handle on a "intermittent" electrical fault on
starting my 98 TJ Wrangler. From cold she starts but the Radio,
windscreen wippers and indicators are dead, more interesting if I turn
off the engine and put the key in the its first position they all
work. With persistantance or time running the electrical fault goes
away.

I've checked the fuses and the obvious wires (steering column) but no
joy.

I don't suppose anyone has seen anything similar?

Thanks in advance.
