Rough start

[OGBobbyJohnson]

4-5x over the last few months I’ve started my 17 EL and it would say check user manual as it ran rough. I stop the engine and restart to which everything works fine. Replaced spark plugs with iridium about 4K a go. Doesn’t throw a code ever. Have 106k miles on it.anyone else having same issue?
