Default Odd no start problem

'90 Seville w/4.5 Most of the time it cranks good but will not start. It gets no spark to the plug wires.
After replacing distrib cap, ign module w/no progress got a distrib from a salvage yard and it started right up, ran good fore 5 -10 mins & quit like someone just turned it off. It will do this occasionally but always shuts down. Most of the time it will crank but
with no spark. Iknow my ign module is good, have 2 coils I can switch andf I'm getting no codes. I did have a E012 but cleared after 1 of the starts and its never returned.

What the hell could be wrong w/this thing? When it does start its like something warms up, fails then shutdown. It always lasts 5-10 mins but most of the time its a no start w/no spark.

Cranks but no spark, well this is a sign that you have a bad crankshaft position sensor.
