I have a 30KW Generac generator that runs on Propane gas.

Customer Question
I have a 30KW...

I have a 30KW Generac generator that runs on Propane gas. During the 15 test run, the engine dies or slows down and then restarts. Sometimes shuts down completely. The maint. technician could not find the problem but thought it might be low pressure from the fuel tank. Test shows pressure okay. Never had a problem before regardless of how much fuel was in the tank. Any suggestions.

Mechanic's Assistant: What's the make and model of the generator? And can you guesstimate how old it is?

Generac model 04948. 12 years old.

Mechanic's Assistant: Do you plan on doing the work yourself?

Probably.

Mechanic's Assistant: Anything else we should know to help you best?

Major problem last year. Maintenance people replace battery charger, circuit board, and two transformers. Generator sometimes just stops when online but will restart. Acts like fuel stops.

I would like to continue. The company technicians here in Oklahoma City don't seem to know what the problem is. I have already spent several hundred dollars on service calls to no avail. The engine that drives the generator is a Ford Ranger V6 that runs on Propane instead of gas. Will appreciate any ideas you come up with. Thanks.

Model number: (###) ###-####Serial number: (###) ###-####Tested the unit again yesterday. Changed fuel tanks. Unit ran for 10 minutes, quit running for 10 seconds, resume running for 3 minutes, stopped for 5 seconds, resumed running and ran for 10 minutes until I shut it down. Never restarted itself , just stalled and resumed running. Generator was not under load. Hope this helps.
