Pick up starts runs a few minutes.at idle shuts off restarts ok,but keeps shutting off.i have replaced both idle sensors,pick up coil in distributor,distributor cap,rotor.plug wires year old and plugs.reset timing runs good,but still shuts off at idle or 1000 rpm.
How many miles on her it may be the timing chain

You might have computer problems.
Does the check engine light come on when it starts to miss?

check timing with timing light , sounds like its out of time , and make sure that the timing marks are not off by one tooth

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

check for minor vacuum leak and map sensor,pcv,egr valve

Did you check for codes. It won't matter what you change if your computer failed. You should of payed the diag fee. You would of saved alot of money.
