I have a 90 Acura Legend. Its been a great car! I've replaced the fuel filter and tuned it up regularly. I got a new car and the Legend has been sitting mostly. Now when I do drive it it runs perfect for a few minutes, then it totally dies either sitting or driving down the road.After a few minutes it starts back up. I don't get it? I replaced the main fuel relay 3 yrs ago. Please help me.. Thanku

Replace the Ignition Control Module (ICM) and coil:
