About to go and put a timing light on it and wait for it to start messing up again and see if it's the timing going crazy that causing the problem. If so is there anything other than the distributor and ecu that would make the timing fluctuate ?
I replaced the distributor and nothing changed, so a bad ecu ? Stupid me can't find the receipt for it so the chance of taking it back is very low, It a freshly reman unit. I even took the relay apart and checked, all looked new inside, fine sand papered the contacts and it's still acting up.

Update later.
