Vertex 4207 Transmit drops out when warm

Working on a 4207 UHF Mobile. First or second transmit are fine with a solid 40 watts on the meter... then it will drop to "0" watts and usually not come back on subsequent transmits... I can put a handheld next to the Mobile and hear a carrier given off on same freq but Bird meter registe...
