Only suggestions, no hard answers. Check the basics first, is fuel pressure consistant? Check the vac line on the regulator to be sure it's dry. Double check the wiring to and from the distributor. Pull the plugs and check their condition and do compression while you're there.
check the EGR to see if it is sticking and while you're at it check the IAC. I would also scan it to see if any soft codes are being set and while there, check the signal inputs from sensors like the TPS, MAP and MAF.
Good luck
