3.7 40V starts, then stops.

Hi All,
Further to my afflicted '8, subsequent trial have derived the problem appears to be temperature related, as when the weather is cold, the car simply won't start and run, it always starts, then cuts out after a couple of seconds.Normally the display won't light, and I have no clocks at all. The other symptom is the clock resets time and date.
Today, I attempted to start it, the clocks lit up, no gauges, but after a couple of attempts, it did start and run, but no fuel gauge, tacho etc, I expect that when I start it in a few minutes, all will be well!
Any suggestions(preferably ones that don't involve checking for fuel with a lighted match!!!!)
Any ideas on where to start, and what to try would be welcome!!
Best Regards,
Steve
