Could be a lot of things. When was the last time you did plugs and wires, fuel filters, basic maintenance?

Have you put a gauge on it and held the throttle open for a bit. I dont mean wide open. Say like 2000 rpm? That would help eliminate any fuel issue.

It has no codes correct? Check engine light work when the key comes on? Then goes out?
