84 digijet stalls then runs fine

[kaalualu]

My 84, recently purchased, has developed a stalling problem. It happens 5 minutes after start up, while driving. A stumble/bog occurs and 10 seconds later engine stalls. After waiting for 10 minutes, it starts right up and operates normally. When I bought vehicle, a few things were needed. ISU was by passed, charcoal canister by passed. Those were both added back into circuit. Timing set, valves adjusted, plugs changed. Grounds cleaned and repaired. Compression check showed 135/130/140/135. Idle is fairly consistant at 850. Runs great, power is good. No other issues.
Any ideas on stalling issue?

Yes, fuel lines replaced, GoWesty kit. Injector seals too.

Check the wiring to the hall effect in the distributor or could be the hall effect itself.

How fast & far are you driving in those 5 minutes?

Do you really have to wait 10 minutes before it restarts? i.e., it will not restart immediately?

Does it eventually settle down and run fine - or does the problem recur indefinitely as you drive?

My digijet was giving me intermittent starting issues. However it would huff and puff trying to start. It turned out to be the idle control unit - but in your case where it is not huffing and puffing I'm not sure if it will help. It wouldn't hurt to try!

Hmm, Temp Sensor 2 going out of value or Open Circuit when just out of Cold Engine spec?
Don't know, just tossing that out there since you can restart it a bit later and you're okay then.

I'm going to try the ISU by pass now.
leaning toward toward templl sensor, can I run unplugged or need a proven one?

By passing Idle stabilizer worked, no stall. Seems a bit low on idle speed...
