Start’s won’t stay running

Drove the Jeep (94 YJ 2.5) came home went to go back out , started but then died. Got it running for about 45 seconds had to feather the throttle. I changed the fuel pressure sensor, no difference. I pulled a vacuum line from what I believe is the MAP sensor ( center fire wall above the vale cover ) this time it ran and didn’t die I managed to get it up the driveway, wife kept chocking the back tire every 2 feet but we made it . Any thoughts would be greatly appreciated 😎

Should I check sensors or the ECM?
if it runs while feathering the throttle it;s probably a clogged IAC just clean the carbon out of it so the engine can get air at idle. If it is full of carbon and the plunger wont move it cant get enough air to idle and will just die.

Fuel pressure? Fuel filter age? Previous refuel date?

That had crossed my mind, I started a new job at the beginning of April. My commute was 40 miles a day round trip now it’s 1.4 miles a day .
Fuel filter is due for replacement, that’s the next step. Appreciate all the advice .
Thanks 😎
Changed the fuel filter it ran for a bit then died. I pulled the vacuum line off the sensor that’s located center fire wall above valve gasket cover, it ran longer than expected . I put my finger over the line and I could feel air being drawn through. I reconnected the line and it died 🤔.
