Have you checked the voltage at the OBD1 port for the OPS, or done a fuel pressure check while idling? I dont know if you have an LP and CRK fuse in the fuse center like mine in 94.

I agree with Robin PMD is going out - I have had them stall 4 times in one
day, then go for 3 weeks without a problem.
Where is your remote mount? Intake?
And to touch on the vented/non vented cap issue, I don't really know why
GM wants a vacuum in there, probably so they could sell more lift pumps as
they wear out from overworking them.
I put a locking gasser cap on mine, and
removed the O-ring so it won't create a vacuum.
