Bought my SRT6 Roadster in early 2011 with 21000 miles on it. After about a year started to have the intermittent problem with it engaging. Changed the inter cooler water pump and solved the problem. Fast forward to 2020 and it went intermittent again (about 74000 miles on car). Change the pump again and drove for just a little while and it started again. Put the car in storage since I was in the middle of building a house, so it sat for awhile. Started to drive again a few months ago and still is intermittent. So put another pump on it and still intermittent. Any ideals of what else may be the cause. I have checked the fuses they are good. Seems very much to be a temperature problem. Works for a little bit then quits then comes back in a little bit. Continues to operate that way.

Thanks.
