"Hello, my 1989 chev 350 wit

"Hello, my 1989 chev 350 with merc cr. has baffeled with a problem I have not been able to solve. It runs great for 30 to 45 minutes, under all conditions and then bucs a little and looses power and stops. It will flash up again in a few minutes and run for a short period and stop again. It is not fuel related, I have changed the filters and ran it off a seperated supply to elimated tank problems. It is not overheating, and all guages read normal.
I do not think it is the cap or wires or plugs, does not miss , just gives three or four bucs and stops either under plane or idle. Going to try a coil, any suggestions, has this happened to any one you know, thanks, help needed for long distance trip that is planned. SOUP"

"Check the cap, if the terminals are grey they are aluminum and get corroded easily, Brass ones are best. You're problem could be a couple things, either the ignition module or the sensor inside the cap, the little wires get corroded and cause problems."
