Car surging at idle no check lights

Hello
Engine running great after timing RxR till today.
At idle car surges from 800 RPM to 0 ,back to 800 and zero back ect
WHEN I give gas to 2000 holds for miliseconds then to zero and dies.
Gas tank cap was openned and vacuum released, tank at 1/4 and there are no
check engine lights on. What now?
PS when I removed MAS from hose, car would start and die, when I disconnect the MAS, and had it out the cr idles real rough.

What now?
Thanks:sad:
