It loses power , then stops, its an 02 with the 8.3, but I am not sure if it is the ISL or the ISC?

Thanks, hadn't thought about the codes, think I will take to Cummins and have them look at it. As for dash warnings, nothing appeared to tell me anything. As for the overflow tank sensor and a possible air in the system problem, do you dismiss that?

Thanks for your input. The coach is now in Fl., parked and will be there thru March. I may talk to Cummins or I may just wait for my return to Mi. in April. What bugs me is I shut down 6 times in the first 150 miles, then it ran flawlessly for the next 1150 miles.

Started for Fl. and Cummins 8.3 shut down 25 miles from home. Just had filters replaced 3 days before and was suspect of air leak, etc. Called a service company who was working on a semi not far from where I was and said he would be there shortly. Waited for half an hour and decided to try to restart. Started right up , called mobile tec back and he recommended trying to drive it to Pilot, which was 2 miles away, that way getting it off busy I94 In Mi. and he would meet me there. He showed up, checked filters, no leaks, and then opened rear access to engine. Looked around and spotted my overflow tank cap was just sitting on it and not screwed on. Also fluid was low. I suspect the shop that I took it to was going to check fluid and forgot. Anyway, he added fluid and suspected the sensor was above the fluid ling and thus the shutdown. I left the Pilot and engine shutdown 5 more times and I was able to coast to a stop off the highway each time. The last time It shut down was in Indy on the Keystone Pkwy. Each time it would shut down completely and then restart almost immediatly. Since it was a Sunday, I decided to stay in Indy and get it serviced the next day. AS it turned out all the campgrounds there were filled and I decided to keep going and stay in a rest area somewhere. As it turned out, it never shut down again all the way to FT. Myers. I did talk to another mobile tech in Perry, Fl. who said he suspected that after filling the tank I should have burped the system by releasing the cap for possible air in the system. From Indy down absolutely no problems.  Any thoughts or suggestions?
