"Sounds like a fuel problem,
1. The pickup may be plugged with shellac. Try blowing some air through the fuel line to the tank.
2. Could be a fuel ine that is collapsing.
3. Could be a loose fuel line clamp that is letting air into the system."

"if gas line was calasping wouldnt' it happen right from the start,? air intrusion into the system /gas line would/should happen quicker also ? im a plumber don't know engines."

When this happened to me it was a loose clamp at the Racor fuel filter. Take it for what it is worth.

"How long do you let it set before it restarts?What did you change that caused the problem,or did the problem come first.
Did you check for spark or fuel when it dies.
What happens above 3800 RPM?"

"I have same problem with my mariah. Runs excellent for 20-30 min, but occasionally dies, and wont restart untill it cools down. Ive checked, and it has no spark when we try and restart it hot.?"

"it was the control module, it was bad, would heat and die at 27 minutes every time, like clock work. hope ths helps. t"

Shuto, by control module are you referring to the Pertronix ignition?
