was running and now it won't stay running more than 20 seconds
after suggestion from sewerzuk (see quote) I have changed fuel filters and cleaned all fuel lines, clean fuel pump filters, checked all 90's, steam cleaned day tank, checked injector return line, made sure all fitting tight at injectors, put a meter and even open IP to see if solenoid was engaging all check out, clean filter in front of IP. no warning lights still only 15 to 20 second. Do i have a bad pump or an air leak

This is almost certainly a fuel problem...
Normal things to check (even if you do see some fuel available at the IP):
1. Leaks in the fuel supply line (including in the fuel filters)
2. Fuel level in the day tank (includes operation of the lift pumps, solenoid valve, and float switch)
3. Clocked/blocked fuel filters and/or fuel line
4. Air in the fuel line
5. Blockage in the fuel return line
6. Faulty/defective injection pump
