1994 indy 500 efi
Got a 94 indy 500 efi. runs great for about 10 miles then starts to bog. get worse and worse to the point whre it was not drivable. Let it sit about a half hour and was able to drive it home but as i got closer to home the bogging came back. Im guessing stator or coils? Thoughts?
 
Those 500efi’s can be problematic. Check the compression in each cylinder. Are the fuel filters original?

There had been quite a few people that converted them over to carbs over the years because they could never solve the issue but there is quite a bit of stuff involved in doing it.
