Customer Question

Hi Dominick,
I have a 2008 Suzuki DF 70TLK8, SN 07001F-882512.
The motor starts fine, but after running for 15-20 minutes it begins to stall. Sometimes it runs well again after some minutes, but it will do the stalling again.
Any advice on what to check?
Thanks.

Hi Edgar, good morning my name is Jason.

Are you able to check and see if the engine has fuel pressure when it stalls, or if pressure drops just before it stalls?

Customer: replied 9 months ago.
No. How do I check?
Expert:  Jason replied 9 months ago.
I''m attaching a file that shows how to check it, see attachment.
Customer: replied 9 months ago.
Got it. I would need to get the pressure gauge set up. I will work with that.Any other tips on possible causes? I have read online that it also could be the vapor lock, the coil that could fail after it gets warm, the fuel pump or the fuel filter.

How did you want to leave this?

I don't understand your question.
Expert:  Jason replied 9 months ago.

Did you want to check fuel pressure and get back to me? Did you have any further questions for me on the issue?

What it sounds like is it sounds like the engine is starving for fuel, I just wanted to prove that theory first by seeing if fuel pressure drops before the motor stalls, does that make sense.

Customer: replied 9 months ago.
I will check the fuel pressure and get back to you with the results. This will take a few days. Thanks.

You are very welcome, let me know how you make out.
