Numbers first. Cat988H S/N BXY00384 Engine C18 S/N RHX00979 Electronic Unit Injectors.
Engine starts fast in morning but when shut off for break or lunch when restarted 15 minutes later starts good then after a few seconds starts stumbling bad like it is running out of fuel then after several seconds takes off and runs great.
I was thinking it was loosing it's prime due to a bad check valve but this seems like it would be worse after setting all night. Usually it is fueled up at night but as it was parked in shop to get new temp. regulators it was not fueled up yesterday and had about 1/2 a tank of fuel, less than it would have when shut down for morning break.
While doing some checking for the overheat problem yesterday I checked for active and stored error codes and there were none.
Any ideas????
