Symptoms of flakey system relay or ign. switch??

My '90 SPG is being weird again; about every third start (old or hot)terrible idle, no throttle response, and then stalls out. On restart it usually behaves normally. When bad it acts like no fuel regulation/pressure. No error codes being logged by the ECU. Good batt. I've done all the ground points inc the one by the ign. switch. Changed AMM, fuel pump is only three months old, full tune, new O2 sensor. Today I pulled the system & pump relays; contacts were a little pitted but not terribly so. I cleaned them up and reinstalled. Same thing happened on the second restart.
Where should I go from here? Can a bad ignition switch do this sot of thing?
