engine losses spark after it warms up
starts again once it has cooled on 1990 Mercedes-Benz 300E

starts fine when cold
checked fuel pressure its good
losses spark when warm and just dies

It's probably the ignition module in the distributor failing, if it is faulty it will produce these exact symtoms. I happens when the motor warms up and the distributor is warm enough. Good luck! Gymover
