Protractor suites are not properly getting executed

I have multiple specs so i created a suite for different specs. Let's take the below scenario.

this is my suite structure in the conf file.

 suites:{
    forms:['specs/requestE.js'],
    search:['specs/findaSpec.js'],
    offers:['specs/offersPrograms.js','specs/destinationsSpec.js'],
    headerfooterlinks:['specs/footerlinksSpec.js','specs/headerMenuSpec.js']

},

When I run each spec individually it works correctly and generates the test results, but when I run the whole suite only the first one is working, others are not getting executed. As a result it gives timeout error.
