I changed the two fuel filters, one at a time and on the 8V92TA Detroit  and filled them with diese before installing them. This is the 8th time in eight years that I have done this with no problems. Well the 9th time is an issue. Strarted the coach up. Ran for about 30 seconds perfectly, no leaks. Then it started running rough, like 1 cylinder was not contributing.  I was unable to raisse the rpm's and shut the motor down. Removed the first filter, looking for perhaps a double gasket situation, but all was good. Same with the 2nd filter. Replaced them one at a time with spare filters, filling the filters with diesel. Now the coach is still a no start. Never had to purge air. I don'tknow how to proceed. Iam avoiding cranking for long periods, trying to avoid damaging the starter with heat. Any suggestions?
