97 Challenger stops frequently

[boat guy]

97 challenger has single 110 hp motor, runs fine for sometimes 10 or 15 mins. sometimes just a few seconds and then stops but then fires up with no hesitation but then the same thing, stops after a few mins. or a few seconds. Sometimes it will stop maybe 10 times in the span of a min. or 2. It has had a new lanyard programed but this didn't help. This problem is driving me crazy can anyone help?

Try cleaning the post with soapy water. I had the same problem and ended up putting in a new post for $50.

Has it been stopping while idling or when you're moving?

Check the exhaust hoses

The hoses can delaminate on the inside and block the exhaust flow. Do the hoses feel soft in any place? They should be very firm from top to bottom. They need to be removed and inspected to be sure they aren't coming apart on the inside. See the photo on the left to see what happens to old hoses.
