92 C-70, throttle body injected 366.
It runs fair for 10 minutes(5 miles or so of hard running). I dump at the elevator and head back for another load... On the way back it stumbles within the first 1/4 mile, "Blah, Blah", then recovers, it will repeat this a few times over the course of a few minutes. It always seems to happen between 2-3000 rpms while accelerating. It hasn't stalled yet, but is enough to make you think you will be walking home.
Any thoughts before I start throwing parts at it? I was thinking a distributor and coil...maybe heat related.
