I had the same problem with my '93 Itasca 454. It seemed to be starving for fuel and only late in the day in Florida when it was warm outside. It did not happen after we left Fl and headed for home [cooler weather] When I got home I flushed the tank and put in a new fuel pump [it was suggested by a chevy mechanic that I had a rusty gas tank and the sock on the fuel pump was plugging up with rust that was falling away after it was shut off for awhile] didn't have a chance to test it. Then it was suggested that the control module in the distributor was going bad. This was a common problem with these engines after 40-50K miles. This made a lot more sense to me being that it only happened when the weather was hot [the engine was not overheating] I am back in Fl now and parked so I have not been able to test it on a hot day. It is a $30 part and not that hard to change so it may be worth a try.
Good Luck
