[urq] Intermittent no start

[Louis-Alain Richard]

Hi there,

Twice in the last month, my car refused to re-start when stopped for a
short period after highway. The first time I bump-started it easily, the
second time I had to wait 5 minutes and it catch normally.

What is the cause of this behaviour ? 
Starter (the 1983 original "big bertha") has been rebuilt 3 years ago,
the ignition switch seems to work fine (I was hearing the click-click of
the hot start pulse relay during the attemps), wiring is tight but
dirty.

Thanks in advance,

Louis-Alain

PS: an overpass fell on an highway near my home yesterday, 5 persons are
dead, 6 more fell in the hole. I've passed under that overpass less than
1 hour before the accident (heading to Tremblant for the NEQ event).
Sometimes, you just feel lucky.
