Hi. I have a Briggs & Stratton 2800PSI gas pressure washer. I can get it to start, but after about 5 min, then it quits. I have cleaned the carb, change oil, changed plug, new gas, cleaned/checked air filter. Nothing will keep it running. Wondering if it may be not enough water pressure, but would that cause it to stop like that? When it runs, it does a good job, but it stops just as you get going. Do you have any other suggestions? Thanks!
