Random engine stalling ????

[tttype]

Car may run 10 seconds or 30 minutes, but will evetually just quite.

Does not sputter or stumble, just stops instantly.

Happens mostly at idle or light load cruising.

Will not fire when trying to restart.

First few times it happened, got out & wiggled ign module wires & it restarted.
(now think this was just luck )

So started checking crank sensor issues



It is now quitting on a regular basis , so did the following
- changed crank sensor
- swapped module
- wiggled all crank & cam sensor wires at idle, no stalling


After stalled , during cranking when it will not fire ;

-Have 10V at module output for cam & crank sensor
- above sensors have ground also
- XFI crank light is steady
- XFI cam light blinks off about every 3 seconds during cranking
- injectors are being pulsed
- have spark @ plugs ( right time I do not know, engine does not pop or backfire though )
- no malfuntion codes show in XFI

Its got fuel & spark,

any one have any ideas ?

If it has fuel and spark it should run. When cranking, is the spark around 10 degrees? What do the plugs look like when iy won't start?

I think we found it !
While checking for injector pulse, the test light was barely lit on the positive inj wire.
Pulled on inj harness connection & light lit right up.

Flaky connection may have been causing problems for a while.
