New problem - 5Ks KZ stalling

[Ben Swann]

Don't overlook the ignition switch.  BTDT 2or3X on different 5ktqs with
similar symptoms.

Suspected lean condition/vaporlock due to temperature extremes - turns out
the switch was overheating.

Ok, so it's not an MC like most of you but it's given me just about 20years
of service with "normal" maintenance. Now comes an interesting problem of
no-start and stalling.

The first case was a no-start while my wife had the car. With 100 degree
weather, I chalked it up to a fuel vapor problem. She had driven several
miles, parked and after 15 minutes could not start up. She waited several
more minutes and it started up with no issues. Second time, I was turning
into a parking lot and downshifted to 2nd when the motorjust quit. I rolled
to the side and it restarted right away.

The car has 147K on it, it's an "86 5ks avant. Now I'm thinking ignition
more than fuel. The only ignition parts replaced (other than plugs) are
wires with perhaps 60K on them. I have new wires, cap and rotor which could
go on. I also have some tappets to replace so was going to do it all at
once. Any ideas from you all? Is this how the hall sensor fails?

Concur on ignition as the most likely area?

Thanks,
