Hi to those who have tried to sort this issue out with me. Finally resolved today and is worth posting the issus incase anyone else has the same issue.
I went right through every cable to and from the gen set. Pulled out the start and pre heat switches and found the start/run switch had intermittent fault. Even pulled the carling switches apart and found contacts were quite burnt. So replaced the switches. Tried to start again and still the same. Ok here it is. My Sea Ray 500 is fitted with a Sea Fire fire fighting/suppression system. The system has a module in the circuit that automatically shuts the engines and genset down in the event of a fire. The module has a series of inbuilt switches that perform the task, one for each engine and one for the genset. As it turns out the switch for the genset was faulty. When you switch the genset to run the switch within the module engages and provides current to the run circuit through the switch to the genset. Unless there is a fire. The module being faulty was switching off after a few minutes. By passed the switch and all runs perfectly. Had it running for oner an hour fully loaded no problem. Have to order a new module which will fix the problem.
