starts fine then after running for 10-15 minutes it quits. Will restart after about 10-15 min then will run for 5-10 and stop again. Had new water pump put in. Seemed to help last year now it is doing the same thing again
Look for shorting plugwires. If there is no spark when it quits, I would suspect your powerpack is heating up and shorting out. In that case you would need to replace the powerpack.
